There is no other herb equivalent to this. In ancient times, Tulsi was considered for Brahmcharaya (celibacy) in India. Ayurveda classifies Holy basil as ‘Rasayana’: a herb that nourishes a person’s growth to perfect health and promotes long life. Health Benefits of Holy basil has been found effective for cancer, diabetes, high cholesterol levels, liver support and protection, hypoglycemic conditions, ulcers, digestion, radiation poisoning etc.

As Tulsi has health benefitting effects by reducing stress and improving both cellular and humoral immunity, its role in treatment of cancer cases may be a new approach in therapy of cancer and in prevention of ill effects of radiation.

Experiment on Tulsi :
An experiment was conducted in which dietary supplementation of fresh tulsi leaves for 30 days led to significant lowering of blood glucose levels . Regular usage of Ocimum sanctum also led to significant increase in levels of superoxide dismutase, reduced glutathione and total thiols, but there was marked reduction in peroxiodised lipid levels as compared to untreated control group. It was found in the experiment that tulsi leaves possess both superoxide and hydroxyl free radical scavenging action. The present observations establish the efficacy of Ocimum sanctum leaves in lowering blood glucose levels and antioxidant property which is predominantly responsible for hypoglycemic effect.
In another experiment conducted on rats, Ocimum sanctum leaves have been shown to exert hepatoprotective effect in paracetamol and carbon tetrachloride induced liver damage in rats. The qualitative analysis of the extracts from the leaf sample of Ocimum sanctum also showed the presence of phytochemical constituents such as tannins, saponin, flavonoids, terpenoid, cardiac glycerides etc.
