Holy Basil Leaf Extract

Also known as: Ocimum sanctum, Holy Basil, Tulsi, Ocimum basilicum, Sweet Basil

Overview

Holy Basil, scientifically known as *Ocimum sanctum*, is a plant native to the Indian subcontinent and is revered in Ayurvedic medicine for its adaptogenic, anti-inflammatory, and antioxidant properties. It is also referred to as Tulsi. The leaves of the plant are commonly used in teas, extracts, and supplements. Holy Basil contains bioactive compounds such as eugenol, ursolic acid, and β-caryophyllene, which are believed to contribute to its therapeutic effects. It is primarily used for stress relief, cognitive enhancement, and as an adaptogen to help the body cope with various stressors. Research on Holy Basil is growing, with an increasing number of human studies exploring its potential benefits, although more systematic reviews are needed to solidify the evidence. The quality of available evidence varies, with some studies showing promising effects, but more rigorous trials are necessary to confirm these findings.

Benefits

Holy Basil extract has shown potential in improving cognitive parameters such as reaction time and error rate in healthy adults, with benefits observed after about 15 days of supplementation. Traditionally, it has been used for stress relief, although specific studies on stress reduction in humans are somewhat limited. Animal studies suggest that basil extracts may help lower blood glucose levels, indicating potential antidiabetic effects. Furthermore, in vitro and animal studies suggest anticancer properties, but human trials are currently lacking. Holy Basil may be particularly beneficial for individuals with lifestyle-related chronic diseases, such as diabetes and metabolic syndrome. While significant improvements in cognitive tests have been observed, effect sizes vary across studies, highlighting the need for further research to determine optimal dosages and specific applications.

How it works

Holy Basil's mechanism of action involves antioxidant, anti-inflammatory, and adaptogenic pathways. It affects the nervous system by enhancing cognitive functions and potentially modulating stress responses. Compounds like eugenol and ursolic acid may interact with various cellular targets to exert their effects. However, there is limited data available on the absorption and bioavailability of Holy Basil's active compounds, indicating a need for further research in this area.

Side effects

Holy Basil is generally considered safe in moderate doses, but high doses may pose risks. The most commonly reported side effect is occasional nausea. Uncommon side effects include potential reproductive toxicity, although this has primarily been observed in animal studies. There are no well-documented rare side effects in humans. Due to limited data, caution is advised when using Holy Basil with medications for diabetes and blood thinners. Pregnant women and individuals with certain reproductive issues should exercise caution due to the potential for reproductive toxicity. It is advisable for pregnant women and individuals with impaired fertility to avoid high doses of Holy Basil.

Dosage

For cognitive benefits, a typical minimum effective dose of Holy Basil extract is around 300 mg per day. Optimal dosage ranges are generally between 300-600 mg per day, although more research is needed to establish precise dosing guidelines. The maximum safe dose is currently unclear, and high doses may increase the risk of adverse effects. There are no specific timing recommendations available for Holy Basil supplementation. Ethanolic extracts have been used in some studies. Bioavailability may vary based on the extraction method and individual factors. No specific cofactors are documented as required for Holy Basil's efficacy.
