Anxiety Relief, Culinary Herb

Holy basil has always been considered to be a tonic, invigorating herb, useful for improving vitality.

Why We Love It

Holy basil, like sweet (culinary) basil, comes from India, where it is revered as the herb sacred to the goddess Lakshmi, wife of Vishnu, the god who preserves life. Tulsi means “matchless,” and the herb has very important medicinal properties—notably its ability to reduce blood- sugar levels. In Indian herbal medicine, holy basil has a wide range of uses, relieving fevers, bronchitis, asthma, stress, and mouth ulcers.

■ Ayurvedic remedy In Ayurvedic medicine, holy basil is chiefly employed for fevers. A classical Indian recipe mixes holy basil, black pepper (Piper nigrum, p. 250), ginger (Zingiber officinale, p. 155), and honey in a remedy that prevents infection and controls high fever.

■ Heart & stress Holy basil is thought to have an affinity with the heart, protecting it from stress and lowering blood pressure and cholesterol levels. It has a reputation for reducing stress and is regarded
as adaptogenic—helping the body to adapt to new demands and stresses.

■ Diabetic remedy The herb’s ability to help stabilize blood-sugar levels makes it useful in the treatment of diabetes.

■ Respiratory problems Holy basil is valuable for respiratory infections, especially colds, coughs, bronchitis, and pleurisy. It also treats asthma.

■ Other uses Juice is extracted and applied to insect bites, ringworm, and skin diseases. It is also used as ear drops for ear infections. Juice or powdered herb helps mouth ulcers to heal.
