Abstract
The pathologies produced by fungi in the oral cavity in recent decades have become a health problem, with factors such as an imbalance of the local microbiota being the cause for their propagation. Conventional antifungal treatments, instead of being beneficial, have generated alterations that have led to antifungal resistance. The aim of this study was to investigate and describe phytotherapy resources as a possible solution to oral antifungal resistance. A bibliographic search was carried out on platforms such as PubMed, Scopus, ScienceDirect, Web of Science, and Google scholar. A total of 248 scientific articles were obtained, of which 108 met the inclusion criteria. Microorganisms of fungal origin currently show resistance to the different antifungals of conventional use, which is undoubtedly altering the oral health of human beings, but there are new therapeutic possibilities such as the active principles of various natural species.

Kaur B, Kumar N, Chawla S, Sharma D, Korpole S, Sharma R, Patel MK, Chopra K, Chaurasia OP, Saxena S. A comparative study of in-vitro and in-silico anti-candidal activity and GC-MS profiles of snow mountain garlic vs. common garlic. J Appl Microbiol 2022; 133:1308-1321. [PMID: 35389539 DOI: 10.1111/jam.15537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 03/09/2022] [Accepted: 03/19/2022] [Indexed: 11/30/2022]
Abstract
AIM The study aimed to profile the volatile phytocomposition of snow mountain garlic (SMG) compared to common garlic and investigate the anti-Candida efficacy against clinically relevant multi-drug resistant isolates of Candida species. METHODS AND RESULTS Herein, SMG has shown significantly superior fungicidal power at 2x-MIC dose against C. albicans and C. glabrata in killing kinetic evaluation unlike fungistatic effect of common garlic. GC-MS headspace-based profiling of SMG showed 5 unique volatile compounds and 5-fold higher content of saponins than common garlic. In an in-silico analysis, Cholesta-4,6-dien-3-ol,(3-beta) was uniquely identified in SMG as a potential inhibitor with high binding affinity to the active site of exo-1,3-betaglucan synthase, an established anti-candida drug target crucial for the biofilm matrix formation, thus suggesting a plausible antifungal mechanism. CONCLUSION The in-vitro and in-silico study established Candida-cidal and anti-biofilm activities of SMG that differentiate it from Candida-static efficacy of common garlic. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report that identifies several phytochemical signatures of SMG along with a potential anti-fungal compound, i.e. Cholesta-4,6-dien-3-ol,(3-beta)-, which appears worthy of detailed studies in future to explore utility of SMG as a fungal phytotherapy agent, especially against drug resistant Candida sp.

Abstract
Allium sativum L. (garlic bulbs) and Allium fistulosum L. (Welsh onion leaves) showed quantitative differences of identified compounds: allicin and alliin (380 µg/mL and 1410 µg/mL in garlic; 20 µg/mL and 145 µg/mL in Welsh onion), and the phenolic compounds (chlorogenic acid, p-coumaric acid, ferulic acid, gentisic acid, 4-hydroxybenzoic acid, kaempferol, isoquercitrin, quercitrin, quercetin, and rutin). The chemical composition determined the inhibitory activity of Allium extracts in a dose-dependent manner, on human normal cells (BJ-IC50 0.8841% garlic/0.2433% Welsh onion and HaCaT-IC50 1.086% garlic/0.6197% Welsh onion) and tumor cells (DLD-1-IC50 5.482%/2.124%; MDA-MB-231-IC50 6.375%/2.464%; MCF-7-IC50 6.131%/3.353%; and SK-MES-1-IC50 4.651%/5.819%). At high concentrations, the cytotoxic activity of each extract, on normal cells, was confirmed by: the 50% of the growth inhibition concentration (IC50) value, the cell death induced by necrosis, and biochemical determination of LDH, catalase, and Caspase-3. The four tumor cell lines treated with high concentrations (10%, 5%, 2.5%, and 1.25%) of garlic extract showed different sensibility, appreciated on the base of IC50 value for the most sensitive cell line (SK-MES-1), and the less sensitive (MDA-MB-231) cell line. The high concentrations of Welsh onion extract (5%, 2.5%, and 1.25%) induced pH changes in the culture medium and SK-MES-1 being the less sensitive cell line.

Abstract
Candida albicans is part of the healthy flora in the oral cavity. It can also cause opportunistic infection, which can be deleterious. The most typical type of chronic oral candidiasis is denture stomatitis, and C. albicans is identified as the most crucial organism in this situation. Due to the development of the resistant form of candida, using conventional drugs can sometimes be ineffective. Herbs and naturally imitative bioactive compounds could become a new source for antimycotic therapy. Several review studies suggest that herbal medicine and natural bioactive compounds have antibacterial, antiviral and antifungal effects. Thus, it is hypothesized that these natural products might have beneficial effects on pathogenic oral fungal flora such as C. albicans. Although the effects of herbs have been investigated as antifungal agents in several studies, to the best of our knowledge, the effects of these natural products on C. albicans have not yet been reviewed. Thus, the aim of this study was to review the anti-candida activity (especially C. albicans in oral candidiasis) of herbal medicines and natural bioactive compounds. It is concluded that, in general, medicinal plants and nutraceuticals such as garlic, green tea, propolis, curcumin, licorice root, cinnamon, resveratrol, ginger, and berberine are useful in the treatment of C. albicans in oral candidiasis and could be considered as a safe, accessible, and inexpensive management option in an attempt to prevent and treat oral diseases. However, most of the evidence is based on the in vitro and animal studies, so more clinical trials are needed.

An Overview on Conventional and Non-Conventional Therapeutic Approaches for the Treatment of Candidiasis and Underlying Resistance Mechanisms in Clinical Strains. J Fungi (Basel) 2020; 6:jof6010023. [PMID: 32050673 PMCID: PMC7151124 DOI: 10.3390/jof6010023] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 02/06/2020] [Accepted: 02/07/2020] [Indexed: 02/06/2023] Open
Abstract
Fungal infections and, in particular, those caused by species of the Candida genus, are growing at an alarming rate and have high associated rates of mortality and morbidity. These infections, generally referred as candidiasis, range from common superficial rushes caused by an overgrowth of the yeasts in mucosal surfaces to life-threatening disseminated mycoses. The success of currently used antifungal drugs to treat candidiasis is being endangered by the continuous emergence of resistant strains, specially among non-albicans Candida species. In this review article, the mechanisms of action of currently used antifungals, with emphasis on the mechanisms of resistance reported in clinical isolates, are reviewed. Novel approaches being taken to successfully inhibit growth of pathogenic Candida species, in particular those based on the exploration of natural or synthetic chemicals or on the activity of live probiotics, are also reviewed. It is expected that these novel approaches, either used alone or in combination with traditional antifungals, may contribute to foster the identification of novel anti-Candida therapies.

Abstract
Since the beginning of the epidemic, human immunodeficiency virus (HIV) has infected around 70 million people worldwide, most of whom reside is sub-Saharan Africa. There have been very promising developments in the treatment of HIV with anti-retroviral drug cocktails. However, drug resistance to anti-HIV drugs is emerging, and many people infected with HIV have adverse reactions or do not have ready access to currently available HIV chemotherapies. Thus, there is a need to discover new anti-HIV agents to supplement our current arsenal of anti-HIV drugs and to provide therapeutic options for populations with limited resources or access to currently efficacious chemotherapies. Plant-derived natural products continue to serve as a reservoir for the discovery of new medicines, including anti-HIV agents. This review presents a survey of plants that have shown anti-HIV activity, both in vitro and in vivo.

Abstract
Garlic has played an important role in culinary arts and remedies in the traditional medicine throughout human history. Parasitic infections represent a burden in the society of especially poor countries, causing more than 1 billion infections every year and leading to around one million deaths. In this study, we investigated the mode of anti-parasitic activity of "wild garlics" Tulbaghia violacea and Allium ursinum dichloromethane extracts against parasites Trypanosoma brucei brucei and Leishmania tarentolae with regard to their already known antimicrobial activity. We also evaluated their cytotoxic potential against human cells. Both extracts showed a relevant trypanocidal and leishmanicidal activity, although L. tarentolae was less sensitive. We determined that the probable mode of action of both extracts is the irreversible inhibition of the activity of Trypanosoma brucei trypanothione reductase enzyme. The extracts showed a mild cytotoxic activity against human keratinocytes. They also exhibited weak-in most cases comparable-antibacterial and antifungal activity. HPLC-MS/MS analysis showed that both extracts are abundant in sulfur compounds. Thus, for the first time, the ability of Allium ursinum and Tulbaghia violacea to kill Trypanosoma sp. and Leishmania sp. parasites, probably by binding to and inactivating sulfur-containing compounds essential for the survival of the parasite, is shown.

Abstract
The phytomedicine Tulbaghia consists of the fresh or dried subterranean organs of various Tulbaghia species. The genus is endemic to Southern Africa and includes about 20 species, of which only T. alliacea and T. capensis are naturally found in the winter rainfall climate area (the Western Cape). The genus forms part of the Alliaceae family and is a geophyte (plants with an underground perennation organ and leaves that die back annually). Their habitat can range from semi-desert to wet and boggy terrain. Wild garlic is most commonly prepared as an infusion or boiled in water and taken orally. Externally, as a medicated bath, wild garlic is used to treat paralysis and rheumatism and to reduce the temperature in a feverish patient. Internally, rhizome or bulb preparations are taken orally to treat fever; as a remedy for colds and influenza, asthma, tuberculosis, and stomach problems; as an antihypertensive; or to expel intestinal worms. It is also used as a prophylactic against winter infections. Rhizome pieces are often placed in castor oil to make eardrops. For fever and high blood pressure, a tea is made from the bulbs or rhizomes and a small cup taken three times daily. The leaves of the plant are used to treat esophageal cancer and may also be eaten as a vegetable. The demand for Tulbaghia in both formal and informal markets has grown exponentially. Sustainable harvesting focuses on only harvesting enough of the plant so that it still has the capacity for self-renewal. However, because both the above-ground and underground parts of Tulbaghia are commonly used in African traditional medicine, destructive harvesting of the whole plant is inevitable, thus necessitating the large-scale organized propagation of these plants. It is therefore important to establish a new strategy for the sustainable harvesting of these plants as commercial crops.

Abstract
BACKGROUND Studies have suggested an increasing practice of concurrent herb-drug consumption. One of the major clinical risks of such concomitant herb-drug use is pharmacokinetic herb-drug interaction (HDI). This is brought about by the ability of phytochemicals to inhibit or induce the activity of metabolic enzymes. The aim of this study was to investigate the potential of the crude aqueous extracts of three popular medicinal herbs used in South Africa to inhibit major cytochrome P450 (CYP) enzymes. MATERIALS AND METHODS The extracts of Bowiea volubilis, Spirostachys africana and Tulbaghia violacea were incubated with human liver microsomes (HLM) to monitor the phenacetin O-deethylation, diclofenac 4'-hydroxylation, S-mephenytoin 4'-hydroxylation and testosterone 6β-hydroxylation as respective probe reactions for CYP1A2, CYP2C9, CYP2C19 and CYP3A4. The inhibitory activity, where observed, was profiled against the extract concentration. RESULTS Extracts of Bowiea volubilis inhibited the metabolic activity of CYP1A2 and CYP3A4 with IC50 values of 92.3 ± 5.5 µg/mL and 8.1 ± 0.6 µg/mL respectively. Similar observation with Spirostachys africana showed inhibitory activity against CYP1A2 and CYP3A4 with respective IC50 values of 14.3 ± 0.6 µg/mL and 47.4 ± 2.4 µg/mL. Tulbaghia violacea demonstrated relatively weak inhibitory activity against CYP1A2 (767.4 ± 10.8 µg/mL) and CYP2C9 (921 ± 15.3 µg/mL). CONCLUSION The results suggest the potential for HDI between the herbs and the substrates of the affected enzymes, if sufficient in vivo concentration is attained.

Aremu AO, Van Staden J. The genus Tulbaghia (Alliaceae)--a review of its ethnobotany, pharmacology, phytochemistry and conservation needs. JOURNAL OF ETHNOPHARMACOLOGY 2013; 149:387-400. [PMID: 23838476 DOI: 10.1016/j.jep.2013.06.046] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2013] [Revised: 06/25/2013] [Accepted: 06/26/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tulbaghia is a monocotyledonous genus of herbaceous perennial bulbs predominantly found in Africa. The approximately 63 species have nutritive, ornamental and medicinal value. For centuries, several Tulbaghia species have found diverse uses in traditional medicine. AIM OF THE REVIEW To evaluate and document the uses, especially the medicinal value of the genus Tulbaghia. The existing gaps in knowledge and possible means for greater development are highlighted. METHODS A comprehensive and detailed literature search using electronic search (for example, Google Scholar, Scirus and Web of Science) and ethnobotanical books was conducted. RESULTS Findings based on their traditional uses and scientific evaluation indicates that Tulbaghia violacea remain the most widely used species. Compiled data indicate their efficacy in several in vitro and in vivo pharmacological properties such as antimicrobial, anti-hypertensive, antioxidant and anti-cancer activities. Some phytochemicals which are partly associated with the exhibited bioactivities have been identified and isolated from Tulbaghia violacea and Tulbaghia alliacea. The increasing high usage especially the underground organs, as well as the incessant reliance on the wild population, will eventually affect their abundance and possibly make them susceptible to extinction. CONCLUSIONS The great potential of the genus Tulbaghia, particularly other less popular species, remain to be exploited. Further studies on the structural activity relationship of some of the isolated compound may improve their biological potency. Their characteristic alliaceous aroma may also be of great interest to the food industry seeking novel source of unusual aromas to satisfy increasing consumer demands. In order to derive the much anticipated benefits from the species without compromising their conservation status, the use of different biotechnological approaches highlighted in this review will certainly guarantee their continuous availability.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tulbaghia violacea Harv. (Alliaceae) is a small bulbous herb which belongs to the family Alliaceae, most commonly associated with onions and garlic. In South Africa, this herb has been traditionally used in the treatment of various ailments, including fever, colds, asthma, paralysis, hypertension and stomach problems. The aim of this study was to evaluate the effect of methanol leaf extracts (MLE) of Tulbaghia violacea on the blood pressure (BP) and heart rate (HR) in anaesthetized male spontaneously hypertensive rats; and to find out the mechanism(s) by which it acts. MATERIALS AND METHODS The MLE of Tulbaghia violacea (5-150mg/kg), angiotensin I human acetate salt hydrate (ang I, 3.1-100μg/kg), angiotensin II human (ang II, 3.1-50μg/kg), phenylephrine hydrochloride (phenylephrine, 0.01-0.16mg/kg) and dobutamine hydrochloride (dobutamine, 0.2-10.0μg/kg) were infused intravenously, while the BP and HR were measured via a pressure transducer connecting the femoral artery and the Powerlab. RESULTS Tulbaghia violacea significantly (p<0.01) reduced the systolic, diastolic, and mean arterial BP; and HR dose-dependently. Ang I, ang II, phenylephrine and dobutamine all increased the BP dose-dependently. The hypertensive effect of ang I and the HR-increasing effect of dobutamine were significantly (p<0.01) decreased by their co-infusion with Tulbaghia violacea (60mg/kg). However, the co-infusion of ang II or phenylephrine with Tulbaghia violacea (60mg/kg) did not produce any significant change in BP or HR when compared to the infusion of either agent alone in the same animal. CONCLUSIONS Tulbaghia violacea reduced BP and HR in the SHR. The reduction in BP may be due to actions of the MLE on the ang I converting enzyme (ACE) and β(1) adrenoceptors.

Abstract
Marasmin, which is especially known from the two South African species Tulbaghia alliacea and Tulbaghia violacea , but was also described for the garlic mushroom Marasmius alliaceus , is the precursor of the thiosulfinate marasmicin. Marasmicin has attracted considerable attention because of its antifungal and tuberculostatic activities. However, many Allium species of the subgenus Melanocrommyum, especially Allium suworowii , are also very rich in marasmin. A. suworowii revealed concentrations of marasmin up to 1.6%, related to the fresh weight of bulbs, and up to 3.0%, related to air-dried fruiting bodies, of the corresponding γ-glutamylmarsmin was found in M. alliaceus. Both species show much higher amounts of marasmin as Tulbaghia and could be considered as natural sources for the isolation of this compound. Further promising Allium species with considerable amounts of marasmin besides other cysteine sulfoxides are Allium stipitatum and Allium altissimum . (R(S),R(C))-Marasmin is typical for the investigated species of the subgenus Melanocrommyum, whereas γ-glutamyl-(S(S),R(C))-marasmin is the only cysteine sulfoxide for the genus Marasmius known until now. Both cysteine sulfoxides were isolated and described as o-phthaldialdehyde (OPA) derivatives. Furthermore, the cysteine sulfoxides methiin, propiin, S-(2-pyrrolyl)-cysteine sulfoxide, eventually S-(2-pyridyl)-cysteine sulfoxide and S-(2-pyridyl)-L-cysteine N-oxide were found.
