Overview
Holy basil (Tulsi), an herb native to India is regarded as one of the most important plants used in Ayurvedic medicine.
It is an erect, much branched sub-shrub 40 - 90 cm tall with hairy stems and simple opposite green leaves that are strongly scented.
Traditionally it is used in bronchial asthma, diarrhea, dysentery, skin diseases, malarial fevers, gastric disorders and in hepatic infections.
The leaves are used against bronchitis, ringworm and earache. It has antioxidant, antibacterial, antiviral, adaptogenic and immune-enhancing properties.
It promotes general health and supports the body's natural defense against stress and illness. It seems to increases endurance, inhibits ulcer formation,
and protects against gamma radiation. The leaves may improve pancreatic beta cell function and enhance insulin secretion. A tincture and infused of
the dried whole plant is made. Pharmacological studies have established a scientific basis for therapeutic uses of this plant.
Constituents
Essential oils (eugenol, methyl eugenol, caryophyllene); sesquiterpenes & monoterpenes viz., bornyl acetate, ß-elemene, methyleugenol,
neral, ß-pinene, camphene, a-pinene etc. : ursolic acid, campesterol, cholesterol, stigmasterol, ß-sitosterol and methyl esters of common fatty acids.
Pharmacology
Recent studies suggest that Tulsi may be a COX-2 inhibitor, like many modern painkillers, due to the high concentration of eugenol (1-hydroxy-2-methoxy-4-allylbenzene).
One study showed it to be an effective treatment for diabetes by reducing blood glucose levels. The same study showed significant reduction in total cholesterol levels when using Holy basil.
Another study showed the beneficial effect on blood glucose levels is due to its antioxidant properties. Holy basil also shows some promise for protection from radiation poisoning and cataracts.
The alcoholic leaf extract of Ocimum sanctum was tested for analgesic activity. The results of the study suggest that the analgesic action is exerted both centrally as well as peripherally
and involves an interplay between various neurotransmitter systems.
The protective effect of the ethanolic leaf extract of Ocimum sanctum on haloperidol induced catalepsy was evaluated. The results suggest that Ocimum has a protective effect against haloperidol-induced
catalepsy, which is comparable to the standard drugs (scopolamine and ondansetron) used for the same purpose. The study indicates that Holy basil could be used to prevent drug-induced extrapyramidal side effects.
Ocimum sanctum leaves have been reported to reduce blood glucose when administered humans with diabetes.
Findings indicate that constituents of O. sanctum leaf extracts have stimulatory effects on physiological pathways of insulin secretion which may underlie its reported antidiabetic action.

Anti-inflammatory, expectorant, analgesic, anti-tumor & antibacterial.
