Abstract
In most cases, cancer develops due to abnormal cell growth and subsequent tumour formation. Due to significant constraints with current treatments, natural compounds are being explored as potential alternatives. There are now around 30 natural compounds under clinical trials for the treatment of cancer. Tulsi, or Holy Basil, of the genus Ocimum, is one of the most widely available and cost-effective medicinal plants. In India, the tulsi plant has deep religious and medicinal significance. Tulsi essential oil contains a valuable source of bioactive compounds, such as camphor, eucalyptol, eugenol, alpha-bisabolene, beta-bisabolene, and beta-caryophyllene. These compounds are proposed to be responsible for the antimicrobial properties of the leaf extracts. The anticancer effects of tulsi (Ocimum sanctum L.) have earned it the title of "queen of herbs" and "Elixir of Life" in Ayurvedic treatment. Tulsi leaves, which have high concentrations of eugenol, have been shown to have anticancer properties. In a various cancers, eugenol exerts its antitumour effects through a number of different mechanisms. In light of this, the current review focuses on the anticancer benefits of tulsi and its primary phytoconstituent, eugenol, as apotential therapeutic agent against a wide range of cancer types. In recent years, tulsi has gained popularity due to its anticancer properties. In ongoing clinical trials, a number of tulsi plant compounds are being evaluated for their potential anticancer effects. This article discusses anticancer, chemopreventive, and antioxidant effects of tulsi.

Abstract
AIM The liver and kidneys are the most sensitive organs to lead exposure. Drugs that inhibit the actions of lead in the liver and kidneys are required to protect them from such an exposure. This study investigates the protective effect of the leaf extract of Ocimum sanctum (OS) against lead acetate-induced nephrotoxicity and hepatotoxicity in mice. MATERIALS AND METHODS A total of 20 male mice were divided into five equal groups for the 24-day testing period. The negative control group was administered Tween-80 1% orally for 24 days. The positive control group was administered Tween-80 1% orally for 24 days and, starting on day 4, 20 mg/kg BW lead acetate orally once a day for 21 days 1 h after the administration of Tween-80 1%. The other three treatment groups were administered BW OS leaf extract orally in the amount of 140, 280, and 560 mg/kg once a day for 24 days and, starting on day 4, 20 mg/kg BW lead acetate orally for 21 days 1 h after the administration of OS leaf extract. On day 25, the mice were sacrificed to assess the levels of blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), serum glutamic-oxaloacetic transaminase (SGOT), and serum glutamic-pyruvic transaminase (SGPT) as well as the histopathological changes. RESULTS The OS leaf extract caused a decrease in the scores for hepatocyte degeneration and portal inflammation (p<0.05) but not for hepatic necrosis (p>0.05) in mice exposed to lead. Similar patterns were observed in the effect of OS leaf extract on the renal morphofunction. The OS leaf extract decreased the scores for hydropic degeneration, tubular necrosis, and glomerular necrosis. The levels of MDA, SGOT, SGPT, BUN, and creatinine decreased in the lead-exposed mice treated with OS leaf extract (p<0.05). CONCLUSION The administration of OS leaf extract has a protective effect against lead acetate-induced hepatotoxicity and nephrotoxicity in mice.

Kumar S, Bouic PJ, Rosenkranz B. In Vitro Assessment of the Interaction Potential of Ocimum basilicum (L.) Extracts on CYP2B6, 3A4, and Rifampicin Metabolism. Front Pharmacol 2020; 11:517. [PMID: 32425779 PMCID: PMC7204527 DOI: 10.3389/fphar.2020.00517] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 04/01/2020] [Indexed: 12/12/2022] Open
Abstract
Ocimum basilicum L. or basilicum is a common culinary herb, used as a traditional medicine for various medical conditions including HIV/AIDS and tuberculosis, in Africa. The objective of this study was to evaluate the effect of methanol, ethanol, aqueous and ethyl acetate extracts of the dried leaves and inflorescence of O. basilicum, on the activity of cytochrome P450 enzymes (CYPs) CYP2B6 and 3A4, as well as esterase-mediated metabolism of rifampicin to 25-O-desacetyl rifampicin (25ODESRIF). Human liver microsomes (HLM) were used to evaluate inhibition and CYP2B6/3A4 mRNA expression HepG2 assays were used to measure induction. Furthermore, the phytoconstituents likely involved in causing the observed effect were analyzed using biochemical tests and LC-MS. The aqueous and methanolic extracts showed reversible and time-dependent inhibition (TDI) of CYP2B6 with TDI-IC50s 33.35 μg/ml (IC50 shift-fold >1.5) and 4.93 μg/ml (IC50 shift-fold >7) respectively, while the methanolic and ethanolic extracts inhibited 25ODESRIF formation (IC50s 31 μg/ml, 8.94 μg/ml). In HepG2 assays, the methanolic and ethanolic extracts moderately induced CYP2B6, 3A4 mRNA with 38%-, 28%-fold shift, and 22%-, 44%-fold shift respectively. LC-MS full scans identified phenols rosmarinic acid [m/z 359 (M-H)-, approximately 2298 mg/L in aqueous extract] and caftaric acid along with flavones salvigenin [m/z 329 (M+H)+, approximately 1855 mg/L in ethanolic extract], eupatorin [m/z 345 (M+H)+, 668.772 mg/L in ethanolic extract], rutin [m/z 609 (M-H)-] and isoquercetin [m/z 463 (M-H)-] and other compounds—linalool [m/z 153 (M-H)-], hydroxyjasmonic acid [m/z 225 (M-H)-], eucommiol [m/z 187 (M-H)-] and trihydroxy octadecenoic acid [m/z 329 (M-H)-, 530 mg/L in ethanolic extract]. The putative gastrointestinal tract (GIT) concentration for all extracts was calculated as 2,400 μg/ml and hepatic circulation concentrations were estimated at 805.68 μg/ml for the aqueous extract, and 226.56 μg/ml for methanolic extract. Based on the putative GIT concentration, estimated hepatic circulation concentration [I] and inhibition constant Ki, the predicted percentile of inhibition in vivo was highest for the aqueous extract on CYP2B6 (96.7%). The observations indicated that O. basilicum extracts may have the potential to cause clinically relevant herb-drug interactions (HDI) with CYP2B6 and rifampicin metabolism in vivo, if sufficient hepatic concentrations are reached in humans.

Abstract
The predominant cause of global morbidity and mortality is lifestyle-related chronic diseases, many of which can be addressed through Ayurveda with its focus on healthy lifestyle practices and regular consumption of adaptogenic herbs. Of all the herbs used within Ayurveda, tulsi (Ocimum sanctum Linn) is preeminent, and scientific research is now confirming its beneficial effects. There is mounting evidence that tulsi can address physical, chemical, metabolic and psychological stress through a unique combination of pharmacological actions. Tulsi has been found to protect organs and tissues against chemical stress from industrial pollutants and heavy metals, and physical stress from prolonged physical exertion, ischemia, physical restraint and exposure to cold and excessive noise. Tulsi has also been shown to counter metabolic stress through normalization of blood glucose, blood pressure and lipid levels, and psychological stress through positive effects on memory and cognitive function and through its anxiolytic and anti-depressant properties. Tulsi's broad-spectrum antimicrobial activity, which includes activity against a range of human and animal pathogens, suggests it can be used as a hand sanitizer, mouthwash and water purifier as well as in animal rearing, wound healing, the preservation of food stuffs and herbal raw materials and traveler's health. Cultivation of tulsi plants has both spiritual and practical significance that connects the grower to the creative powers of nature, and organic cultivation offers solutions for food security, rural poverty, hunger, environmental degradation and climate change. The use of tulsi in daily rituals is a testament to Ayurvedic wisdom and provides an example of ancient knowledge offering solutions to modern problems.

Abstract
Ocimum sanctum L. (Lamiaceae) is found throughout India and in many parts of world. O. sanctum is used for the treatment of various health indications. In this lieu, it is of prime importance to investigate the safety aspects of the plant. Hence, the present study was conducted to investigate the possible genotoxic potential and acute oral toxicity of the extract of O. sanctum (OciBest™). The standard battery of in vitro genotoxicity tests, namely bacterial reverse mutation, chromosome aberration and micronucleus (MN) tests were employed to assess the possible mutagenic activity. The results showed that OciBest™ (7.9-2500.0 µg/mL) did not increase the number of histidine revertant colonies in Salmonella typhimurium strains (TA98 and TAMix) with and without exogenous metabolic activation (S9). OciBest™ (10.0-100.0 µg/mL) did not show structural chromosomal aberrations or increase in MN induction, with and without S9, at the tested dose range in both 4-h and 18-h exposure cell cultures. Thus, OciBest™ is not genotoxic in bacterial reverse mutation, chromosomal aberration and MN tests. In an acute oral toxicity test, rats were treated with 5 g/kg of OciBest™ and observed for signs of toxicity for 14 days and the results did not show any treatment-related toxic effects to Wistar rats.

Abstract
Ocimum sanctum L. or Ocimum tenuiflorum L, commonly known as the Holy Basil in English or Tulsi in the various Indian languages, is a important medicinal plant in the various traditional and folk systems of medicine in Southeast Asia. Scientific studies have shown it to possess antiinflammatory, analgesic, antipyretic, antidiabetic, hepatoprotective, hypolipidemic, antistress, and immunomodulatory activities. Preclinical studies have also shown that Tulsi and some of its phytochemicals eugenol, rosmarinic acid, apigenin, myretenal, luteolin, β-sitosterol, and carnosic acid prevented chemical-induced skin, liver, oral, and lung cancers and to mediate these effects by increasing the antioxidant activity, altering the gene expressions, inducing apoptosis, and inhibiting angiogenesis and metastasis. The aqueous extract of Tulsi and its flavanoids, orintin, and vicenin are shown to protect mice against γ-radiation-induced sickness and mortality and to selectively protect the normal tissues against the tumoricidal effects of radiation. The other important phytochemicals like eugenol, rosmarinic acid, apigenin, and carnosic acid are also shown to prevent radiation-induced DNA damage. This review summarizes the results related to the chemopreventive and radioprotective properties of Tulsi and also emphasizes aspects that warrant future research to establish its activity and utility in cancer prevention and treatment.

Abstract
The present study was conducted to investigate the lipid-lowering and antioxidative activities of Ocimum sanctum L. (OS) leaf extracts in liver and heart of rats fed with high-cholesterol (HC) diet for seven weeks. The results shows that OS suppressed the high levels of serum lipid profile and hepatic lipid content without significant effects on fecal lipid excretion. Fecal bile acids excretion was increased in HC rats treated with OS. The high serum levels of TBARS as well as AST, ALT, AP, LDH, CK-MB significantly decreased in HC rats treated with OS. OS suppressed the high level of TABARS and raised the low activities of GPx and CAT without any impact on SOD in the liver. As for the cardiac tissues, OS lowered the high level of TABARS, and raised the activities of GPx, CAT, and SOD. Histopathological results show that OS preserved the liver and myocardial tissues. It can be concluded that OS leaf extracts decreased hepatic and serum lipid profile, and provided the liver and cardiac tissues with protection from hypercholesterolemia. The lipid-lowering effect is probably due to the rise of bile acids synthesis using cholesterol as precursor, and antioxidative activity to protect liver from hypercholesterolemia.

Abstract
The present study investigates the protective effect of methanol extract of Ocimum gratissimum (MOEG) and Ocimum canum (MOEC) from Southern Africa on the oxidative stress induced by alcohol consumption. Male Wistar rats weighing 200-250 g were divided into six groups of six rats each as follows: the normal control group was administered distilled water, the ethanol control was administered ethanol (5 g/kg), and experimental groups EX1 and EX3 were fed ethanol (5 g/kg) plus MOEG and MEOC (100 mg/kg), respectively. Two other experimental groups, EX2 and EX4, were administered MEOG and MEOC (100 mg/kg), respectively, for 30 days. At the end of the experiment, rats were sacrificed, and blood was collected to assay thiobarbituric acid-reactive substances (TBARS), reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and vitamins E and C. Results indicated a significant reduction in the levels of TBARS, ALT, and AST and a significant increase in the levels of GSH and vitamins E and C. The level of vitamin E is greater with MOEG treatment, whereas the vitamin C level goes up with MOEC treatment. A marked improvement occurred in the activities of CAT and SOD in groups EX1 and EX3 compared to the levels with group EC. Thus the results indicated a significant protection by these extracts against ethanol-induced hepatotoxicity (P <or= .05). Again the groups that were treated with extracts only (EX2 and EX4) showed low levels of TBARS, ALT, and AST, which clearly indicates the extract had no toxic effects on hepatocytes. Comparison of results for these two Ocimum species showed no significant difference except in the levels of vitamins E and C with two treatments. Thus there is a possibility that O. canum might be participating through vitamin C and O. gratissimum through vitamin E.
