Abstract
Cancer, as one of the most life-threatening diseases, has attracted the attention of researchers to develop drugs with minimal side effects. The bioactive macromolecules, such as the polysaccharides, are considered the potential candidates against cancer due to their anti-tumor activities and non-toxic characteristics. The present review provides an overview on polysaccharides' extraction, isolation, purification, mechanisms for their anti-tumor activities, structure-activity relationships, absorption and metabolism of polysaccharides, and the applications of polysaccharides in anti-tumor therapy. Numerous research showed extraction methods of polysaccharides had a significant influence on their activities. Additionally, the anti-tumor activities of the polysaccharides are closely related to their structure, while molecular modification and high bioavailability may enhance the anti-tumor activity. Moreover, most of the polysaccharides exerted an anti-tumor activity mainly through the cell cycle arrest, anti-angiogenesis, apoptosis, and immunomodulation mechanisms. Also, recommendations were made to utilize the polysaccharides against cancer.

A case of improvement of clozapine-induced low leukocyte counts by adenine, cepharanthin and ninjin-yoei-to in a patient with treatment-resistant schizophrenia. J Pharm Health Care Sci 2021; 7:45. [PMID: 34852834 PMCID: PMC8638374 DOI: 10.1186/s40780-021-00227-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 10/11/2021] [Indexed: 02/05/2023] Open
Abstract
Background Although clozapine is the optimal drug for patients with treatment-resistant schizophrenia, the drug has harmful adverse effects such as leukopenia. Adenine and cepharanthine are known to be effective for radiation- or drug-induced leukopenia. Furthermore, ninjin-yoei-to, a Chinese herbal medicine, augments the production of granulocyte-macrophage colony-stimulating factor. Thus, these drugs may be useful for clozapine-induced leukopenia. Case presentation A 21 years-old woman with schizophrenia was hospitalized for initiation of clozapine treatment. Despite concomitant use of adenine, cepharanthine, and lithium carbonate having activities of increasing leukocytes, a decrease in leukocyte counts occurred after the initiation of clozapine. Additional administration of ninjin-yoei-to increased leukocyte counts, which prevented the development of leukopenia. Conclusions This is the first case that concomitant use of adenine, cepharanthin, and ninjin-yoei-to exhibited the effectiveness of reversing the decrease in leukocytes caused by clozapine. Monitoring leukocyte counts and preventing leukopenia are essential for successful treatment with clozapine for refractory schizophrenia. These medicines may be a potential option for preventing clozapine-induced leukopenia.

Abstract
Angelica sinensis polysaccharide (ASP) is one of the main active components of Angelica sinensis (AS) that is widely used in traditional Chinese medicine. ASP is water-soluble polysaccharides, and it is mainly composed of glucose (Glc), galactose (Gal), arabinose (Ara), rhamnose (Rha), fucose (Fuc), xylose (Xyl) and galacturonic acid (GalUA). The extraction methods of ASP include hot water extraction and ultrasonic wave extraction, and different extraction methods can affect the yield of ASP. ASP has a variety of pharmacological activities, including hematopoietic activity, promoting immunity, antitumor, anti-inflammatory, antioxidant, anti-aging, anti-virus, liver protection, and so on. As a kind of natural polysaccharide, ASP has potential application as drug carriers. This review provides a comprehensive summary of the latest extraction and purification methods of ASP, the strategies used for monosaccharide compositional analysis plus polysaccharide structural characterization, pharmacological activities and drug carrier applications, and it can provide a basis for further study on ASP.

Abstract
Polysaccharide is one of the necessary macromolecules in life activities, and it is also a very promising natural product for tumor prevention and treatment. In this study, two homogeneous polysaccharides (APS-4I and APS-4II) were isolated from Angelica sinensis (Oliv.) Diels. APS-4I was a linear glucan with molecular weight of 16.1 kDa, which was composed of 88.4% α-1,6-Glcp, 4.1% α-1,2-Glcp, 3.9% α-1,3-Glcp, and 2.8% α-T-Glcp. APS-4II was a novel polysaccharide with molecular weight of 11.1 kDa, which consisted of 55.4% α-1,6-Glcp, 10.4% α-1,3,5-Araf, 8.7% α-T-Araf, 9.2% α-1,5-Araf, 4.0% α-1,3-Araf, 3.6% α-1,4-Galp, and 9.1% β-1,3-Galp. NMR results demonstrated that APS-4II has a backbone composed of →6)-α-Glcp-(1 → 6)-α-Glcp-(1 → 5)-α-Araf-. (1 → 5)-α-Araf-(1 → 3,5)-α-Araf-(1 → 3)-β-Galp-(1 → 3)-β-Galp-(1 → 4)-α-Galp-(1 → 3)-α-Araf-(1 → 3,5)-α-Araf-(1→. Both APS-4I and APS-4II inhibited the tumor growth of B16-bearing mice, and the suppressive effect of APS-4II reached 64.7 ± 7.3%. Meanwhile, there were higher lymphocyte numbers and the levels of IL-2, IFN-γ, and TNF-α in peripheral blood of APS-4II-treated mice than those in APS-4I-treated mice. Furthermore, APS-4II showed a higher inhibitory effect on the proliferation of B16 cells and stronger promoting effects on the proliferation of splenocytes, the phagocytosis of peritoneal macrophages, and the cytotoxicity of NK cells. These results demonstrated that APS-4II could be a promising therapeutic agent for melanoma.

Abstract
Prunus armeniaca gum exudate (PAGE) is obtained from the trunk branches of apricot trees. PAGE is a high-molecular-weight polysaccharide with arabinogalactan structure. The physicochemical and rheological characteristics of this gum have been investigated in various researches. PAGE offers a good potential for use as an emulsifying, binding, and stabilizing agent in food and pharmaceutical industries. It also can be used as an organic additive in tissue culture media, synthesizing of metallic nanoparticles, binding potential in tablets, antioxidant agent, and corrosion inhibitor. For desirable emulsifying, stabilizing, shelf life-enhancing properties, and antioxidant activity of PAGE, it can be used as additive in many foods. We present here a comprehensive review on the existing literatures on characterization of this source of polysaccharide to explore its potential applications in various systems.

Abstract
The intestinal mucosal barrier plays an important role in systemic immune functions. This study aimed to find the mechanism of peptide from Alaska Pollock (APP) on intestinal mucosal immunity in mice induced by cyclophosphamide (Cy). Cy-induced decreases of body weight and index of immune organ were significantly improved by APP as compared with Cy group (p < 0.05). APP could promote the secretion of SIgA and IgA on intestinal mucosa (p < 0.05) and mainly had an impact on the final differentiation of IgA+ B cell, thereby promoting the secretion of plasma cells, which can be corroborated by the increases of IL-6 and IL-10 (p < 0.05). APP with high immune activity was separated and two peptides were purified and identified as Gly–Val–Ile–Lys and Ala–Cys–Asn–Gly–Arg. Therefore, APP can be considered as beneficial ingredients to protect the intestinal barrier disruption induced by Cy.

Abstract
The most crucial complication related to doxorubicin (DOX) therapy is nonspecific cytotoxic effect on healthy normal cells. The clinical use of this broad-spectrum chemotherapeutic agent is restricted due to development of severe form of cardiotoxicity, myelosuppression, and genotoxicity which interfere with therapeutic schedule, compromise treatment outcome and may lead to secondary malignancy. 3,3'-diindolylmethane (DIM) is a naturally occurring plant alkaloid formed by the hydrolysis of indolylmethyl glucosinolate (glucobrassicin). Therefore, the present study was undertaken to investigate the protective role of DIM against DOX-induced toxicity in mice. DOX was administered (5 mg/kg b.w., i.p.) and DIM was administered (25 mg/kg b.w., p.o.) in concomitant and 15 days pretreatment schedule. Results showed that DIM significantly attenuated DOX-induced oxidative stress in the cardiac tissues by reducing the levels of free radicals and lipid peroxidation, and by enhancing the level of glutathione (reduced) and the activity of antioxidant enzymes. The chemoprotective potential of DIM was confirmed by histopathological evaluation of heart and bone marrow niche. Moreover, DIM considerably mitigated DOX-induced clastogenicity, DNA damage, apoptosis, and myeloid hyperplasia in bone marrow niche. In addition, oral administration of DIM significantly (p < .05) stimulated the Nrf2-mediated activation of antioxidant response element (ARE) pathway and promoted expression of ARE-driven cytoprotective proteins, HO-1, NQO1, and glutathione-S-transferase (GST). In connection with that, DIM significantly attenuated DOX-induced apoptosis by upregulation of Bcl-2 expression and downregulation of Bax and caspase-3 expression. Thus, this study suggests that DIM has promising chemoprotective efficacy against DOX-induced toxicity and indicates its future use as an adjuvant in chemotherapy.

Abstract
In many parts of the world, there continues to be a long-standing tradition of prescribing herbal products for a range of gastrointestinal conditions. Scientific evidence supporting the use of all herbal preparations is imperfect, however, and available studies are plagued by methodological limitations. For functional gastrointestinal disorders, there is limited evidence supporting the use of some well-characterized preparations. A number of herbals have immunomodulatory activity, and in inflammatory bowel disease there are limited positive placebo-controlled trials; other studies used active controls with suboptimal doses of the comparators. Like all drugs, herbals can lead to serious adverse events (eg, hepatic failure). Quality control is a serious issue to consider when prescribing herbal medicines. Many herbal preparations are marketed without evidence for stringent adherence to good manufacturing practice guidelines. Unpredictable environmental conditions may affect the composition and the concentration of the active ingredients of plant extracts. Further, commercial herbal products usually combine a variable plethora of chemical families with possible medicinal utility. While some of these ingredients might be of benefit, the concentration and dose of these constituents needs to be closely monitored. Physicians and regulators need to remain very cautious about the use of herbal remedies. Appropriate scientific evidence for the claimed clinical benefits should become mandatory worldwide, and the standards for production and safety monitoring should comply with established standards for chemically defined products. If these principles were adopted, the full value of herbal remedies may come to light, particularly as the individually bioactive compounds present in these preparations become recognized.

Abstract
Hericium erinaceus (HEP) is a notable medicinal fungus grown in China and other oriental countries. Polysaccharides from HEP have recently attracted considerable attention due to their numerous physiological activities. The objective of this study was to evaluate the anti-fatigue activity of HEP in a mouse model. After one week of acclimation, mice were randomly divided into four groups: a control group, a low-dose HEP-treated group, a moderate-dose HEP-treated group, and a high-dose HEP-treated group. The treated groups received HEP (50, 100 and 200 mg/kg, ig), while the control group received saline solution. Following treatment for 28 days, the mice performed a forced swimming test until they were exhausted, then the exhaustive swimming time was recorded along with certain biochemical parameters related to fatigue, including blood lactic acid (BLA), serum urea nitrogen (SUN), tissue glycogen, superoxide dismutase (SOD), glutathione peroxidase (GPx) and malondialdehyde (MDA). These results suggested that HEP has significant anti-fatigue activity by decreasing BLA, SUN and MDA content, as well as increasing tissue glycogen content and antioxidant enzyme activity. Based on these results, this study provided theoretical support for the application of HEP in the field of sports nutrition.

Abstract
Angelica sinensis has antioxidative and neuroprotective effects. In the present study, we aimed to determine the neuroprotective effect of polysaccharides isolated from Angelica sinensis. In a preliminary experiment, Angelica sinensis polysaccharides not only protected PC12 neuronal cells from H2O2-induced cytotoxicity, but also reduced apoptosis and intracellular reactive oxygen species levels, and increased the mitochondrial membrane potential induced by H2O2 treatment. In a rat model of local cerebral ischemia, we further demonstrated that Angelica sinensis polysaccharides enhanced the antioxidant activity in cerebral cortical neurons, increased the number of microvessels, and improved blood flow after ischemia. Our findings highlight the protective role of polysaccharides isolated from Angelica sinensis against nerve cell injury and impairment caused by oxidative stress.

Wen Y, Li J, Tan Y, Qin J, Xie X, Wang L, Mei Q, Wang H, Magdalou J, Chen L. Angelica Sinensis polysaccharides stimulated UDP-sugar synthase genes through promoting gene expression of IGF-1 and IGF1R in chondrocytes: promoting anti-osteoarthritic activity. PLoS One 2014; 9:e107024. [PMID: 25202993 PMCID: PMC4159308 DOI: 10.1371/journal.pone.0107024] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2014] [Accepted: 08/06/2014] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Osteoarthritis (OA) is a chronic joints disease characterized by progressive degeneration of articular cartilage due to the loss of cartilage matrix. Previously, we found, for the first time, that an acidic glycan from Angelica Sinensis Polysaccharides (APSs), namely the APS-3c, could protect rat cartilage from OA due to promoting glycosaminoglycan (GAG) synthesis in chondrocytes. In the present work, we tried to further the understanding of ASP-3c's anti-OA activity. METHODOLOGY/PRINCIPAL FINDINGS Human primary chondrocytes were treated with APS-3c or/and recombinant human interleukin 1β (IL-1β). It turned out that APS-3c promoted synthesis of UDP-xylose and GAG, as well as the gene expression of UDP-sugar synthases (USSs), insulin like growth factor 1 (IGF1) and IGF1 receptor (IGF1R), and attenuated the degenerative phenotypes, suppressed biosynthesis of UDP-sugars and GAG, and inhibited the gene expression of USSs, IGF1 and IGF1R induced by IL-1β. Then, we induced a rat OA model with papain, and found that APS-3c also stimulated GAG synthesis and gene expression of USSs, IGF1 and IGF1R in vivo. Additionally, recombinant human IGF1 and IGF1R inhibitor NP-AEW541 were applied to figure out the correlation between stimulated gene expression of USSs, IGF1 and IGF1R induced by APS-3c. It tuned out that the promoted GAG synthesis and USSs gene expression induced by APS-3c was mediated by the stimulated IGF1 and IGF1R gene expression, but not through directly activation of IGF1R signaling pathway. CONCLUSIONS/SIGNIFICANCES We demonstrated for the first time that APS-3c presented anti-OA activity through stimulating IGF-1 and IGF1R gene expression, but not directly activating the IGF1R signaling pathway, which consequently promoted UDP-sugars and GAG synthesis due to up-regulating gene expression of USSs. Our findings presented a better understanding of APS-3c's anti-OA activity and suggested that APS-3c could potentially be a novel therapeutic agent for OA.

EXPERIMENTAL AND TOXICOLOGIC PATHOLOGY : OFFICIAL JOURNAL OF THE GESELLSCHAFT FUR TOXIKOLOGISCHE PATHOLOGIE 2013; 65:27-34. [PMID: 21652192 DOI: 10.1016/j.etp.2011.05.005] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2010] [Revised: 10/27/2010] [Accepted: 05/07/2011] [Indexed: 11/23/2022]
Abstract
The alga Sargassum dentifolium (Turner) C. Agardh, belongs to Sargassaceae, is a brown seaweed in red sea shores in Egypt. This work aimed to extract different water-soluble polysaccharide extracts (E1, E2, and E3) from S. dentifolium and to investigate their protective effect against cyclophosphamide (CP)-induced genotoxicity. Mice bone marrow cells (BMCs) were collected and analyzed for the chromosomal aberration, micronucleated BMCs (MN-BMCs), the mitotic index, DNA fragmentation by comet assay, and histone deacetylases (HDACs), and radical scavenging capacity of extracts was evaluated by the oxygen radical absorbance capacity assay. The results indicated that E2 and E3 significantly inhibited CP-induced multiple chromosomal aberrations, where E1 and E3 significantly suppressed the number of CP-induced formation of tetraploidy. The extracts prohibited the cytotoxic effect of CP and recovered the mitotic activity, whereas E1 possessed the highest recovery and mitosis. In absence of MN, CP induced formation of bi- and poly-nucleated BMCs. E1 prohibited CP-induced formation of bi-nucleated BMCs, while E2 and E3 prohibited CP-induced formation of poly-nucleated BMCs. CP-induced MN-BMCs were accompanied with mono-, bi- and poly-nucleated cells. E1 and E3 remarkably suppressed mono-nucleated MN-BMCs, while E2 inhibited bi-nucleated MN-BMCs. All the extracts significantly inhibited the CP-induced formation of poly-nucleated MN-BMCs. CP-induced DNA fragmentation was inhibited by all extracts, where E1 was the strongest inhibitor as concluded from the comet tail moment. All the extracts were strong OH scavengers, while only E3 was ROO scavenger. The results revealed a drastic decline in HDACs activity by E1 and E3. In conclusion, S. dentifolium polysaccharide extracts E1 and E3 possessed a potential anti-genotoxic and a promising anti-mutagenic activity.

Abstract
Taking into account the rising trend of the incidence of cancers of various organs, effective therapies are urgently needed to control human malignancies. However, almost all of the chemotherapy drugs currently on the market cause serious side effects. Fortunately, several previous studies have shown that some non-toxic biological macromolecules, including polysaccharides and polysaccharide-protein complexes, possess anti-cancer activities or can increase the efficacy of conventional chemotherapy drugs. Based on these encouraging observations, a great deal of effort has been focused on discovering anti-cancer polysaccharides and complexes for the development of effective therapeutics for various human cancers. This review focuses on the advancements in the anti-cancer efficacy of various natural polysaccharides and polysaccharide complexes in the past 5 years. Most polysaccharides were tested using model systems, while several involved clinical trials.

Abstract
In this study cyclophosphamide was used to prepare the blood-deficient model. The red blood cell count and hemoglobin content were measured. The experimental chickens presented the symptoms of blood-deficient syndrome, dullness, shrinkinginto oneself, broken winded, loose feather, waxy eyelid, and pale tongue. At the same time, red blood cell count and hemoglobin content decreased significantly. Angelica polysaccharide as the effective component of Angelica Sinensis could significantly increase the red blood cell count and the hemoglobin content of blood-deficient chickens. The results indicated that cyclophosphamide could significantly reduce the red blood count and hemoglobin content, and make the ideal blood-deficient model successfully. Angelica polysaccharide had the function of enriching blood in different ways. On the one hand Angelica polysaccharide enriched he blood directly, increased the number of RBC and hemoglobin; on the other hand it regulated the hematopoietic factors, enriched the blood indirectly.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Angelica sinensis (AS) is a Chinese herbal medicine traditionally used in prescriptions for replenishing blood and treating abnormal menstruation and other women's diseases. AIM OF THE STUDY This study aimed to separate and identify the major hematopoietic fraction from Angelica sinensis polysaccharides (ASPS), and to investigate the myeloprotective activity of the major bioactive fraction of ASPS as a possible supporting agent for cancer treatments. MATERIALS AND METHODS The ASPS was fractionated with DEAE-Sepharose CL-6B column to obtain four fractions (F1, F2, F3 and F4). Each fraction was cultured with human peripheral blood mononuclear cells (MNCs) to collect conditioned medium (CM). The hematopoietic ability of various MNC-CM was then evaluated by the colony-forming assay on CD34(+) cells collected by the MACS method from human umbilical cord blood (UCB). In myeloprotective experiment, Adriblastina was used to act as the myelosuppressive agent. The monosaccharide composition of ASPS was analyzed by high-performance anion-exchange chromatography-pulse amperometric detector. RESULTS The F2 fraction, which was found to have the highest hematopoietic activity, stimulated the human peripheral blood MNCs to secret GM-CSF and IL-3. F2 could also protect the hematopoietic function of CD34(+) cells from Adriblastina. F2 occupies 19% of ASPS and contains 0.53% protein. The monosaccharide composition of F2 was arabinose (51.82%), fructose (1.65%), galactose (29.96%), glucose (4.78%) and galacturonic acid (14.80%), with molecular weight 2.5-295 kDa. CONCLUSIONS The bioactive fraction identified and fractionated from ASPS may be used as a health-promoting agent for anemia patients and cancer patients under chemoradiation treatment.

Abstract
This article reviews the evidence of clinical efficacy of Traditional Chinese Medicine (TCM). Extracts from single herbs have been studied by the conventional path of drug discovery to become useful drugs in Western Medicine (WM), testifying to the pharmacological activity of herbs used in TCM formulations. Complex formulations prescribed in accordance to the principles of TCM have been in use for centuries. Much effort has been made in proving its efficacy by the criteria of Evidence Based Medicine (EBM). Problems peculiar to adopting such an approach for TCM is discussed, including issues inherent to TCM as well as the lack of well conducted randomised controlled trial to provide robust evidence. As a result the purported efficacy of TCM treatment for many conditions could not be validated by EBM criteria. A selection of studies and meta-analyses providing convincing evidence to the efficacy of some TCM treatment is cited in this review. Improved methodology and reporting in TCM clinical trials will be essential in establishing the role of TCM in the management of certain defined diseases and complementing current Western medical treatment.

Abstract
Cyclophosphamide, an antineoplastic drug effective against a wide variety of cancers is cytotoxic to normal cells also. Ascorbic acid (vitamin C) at higher concentrations possesses cytotoxic effects and it can also enhance the cytotoxicity of 5-fluorouracil in a dose-dependent manner in mouse lymphoma. In the present study, effect of cyclophosphamide treatment alone and in combination with ascorbic acid in vivo on the ultrastructure and some biochemical changes in Dalton's lymphoma tumor cells were investigated. Cyclophosphamide treatment causes disappearance of cell membrane processes, thickening and reduction in the number of mitochondrial cristae as well as the manifestation of rounded shape of mitochondria. The combination treatment with ascorbic acid plus cyclophosphamide caused further changes in tumor cells showing disintegration in the cell surface membrane, disruption in the nuclear membrane and roundish mitochondria with reduction and disruption in the mitochondrial cristae. The observed ascorbic acid plus cyclophosphamide-mediated decrease in reduced glutathione (GSH) in tumor cells may play an important role in the antitumor activity of cyclophosphamide by weakening cellular antioxidant-mediated defense mechanism, thereby increasing tumor cell's susceptibility to cell death. The cyclophosphamide-mediated decrease in lactate dehydrogenase activity in tumor cells and simultaneous increase in ascites supernatant may possibly indicate alteration in the membrane permeability of tumor cells for lactate dehydrogenase as well as tumor cell injury. Further investigation should determine detailed mechanism(s) involved in cyclophosphamide-induced ultrastructural and biochemical changes in tumor cells.

Abstract
MYC proteins (c-MYC, MYCN, and MYCL) regulate processes involved in many if not all aspects of cell fate. Therefore, it is not surprising that the MYC genes are deregulated in several human neoplasias as a result from genetic and epigenetic alterations. The near "omnipotency" together with the many levels of regulation makes MYC an attractive target for tumor intervention therapy. Here, we summarize some of the current understanding of MYC function and provide an overview of different cancer forms with MYC deregulation. We also describe available treatments and highlight novel approaches in the pursuit for MYC-targeting therapies. These efforts, at different stages of development, constitute a promising platform for novel, more specific treatments with fewer side effects. If successful a MYC-targeting therapy has the potential for tailored treatment of a large number of different tumors.

Abstract
UNLABELLED Angelica sinensis is a Chinese medicinal herb for treating gynecological and gastrointestinal disorders, and also in conjunction with cancer chemotherapy. AIM OF THE STUDY In the present study, the cytotoxic and anti-proliferative effects of three main Angelica sinensis phthalides, namely n-butylidenephthalide (BLP), senkyunolide A (SKA) and z-ligustilide (LGT), and their synergy on colon cancer HT-29 cells were investigated. Moreover, the results obtained in both human colon cancer HT-29 and normal colon CCD-18Co cells were compared for the investigation of selectivity. MATERIALS AND METHODS MTT and [3H] thymidine incorporation assays were used for the evaluation of cytotoxic and anti-proliferative effects, respectively. Interactions among phthalides were determined by median-effect analysis. RESULTS All three phthalides dose-dependently decreased cell viability more potently in HT-29 than in CCD-18Co cells. The IC50 values for inhibition of cell proliferation for SKA, LGT and BLP were 54.17+/-5.10, 60.63+/-6.79 and 236.90+/-18.22microM, respectively, in HT-29 cells. Angelica sinensis extract demonstrated significant synergy in inhibiting cell proliferation. CONCLUSIONS The three phthalides might have anti-cancer potential, yet the phthalides, in combination with other ingredients in Angelica sinensis extract, display significant synergy leading to a stronger anti-tumor effect.
