Holy basil is an aromatic plant in the same family as the more familiar sweet basil, which you can find in pizzas and other cooked food. Holy basil, however, has been cultivated for use in religious and folk medicine settings.
Ocimum tenuiflorum or Ocimum sanctum is the scientific name of the plant. Holy basil is also known as tulsi, tulasi, and Queen of the Herbs. To identify holy basil, look for deeply veined green leaves and pale purple flowers. When eaten, expect a bold peppery taste.
Native to north-central India, the herb has a long cultivation history across Southeast Asia. Today it grows in Australia, the Middle East, and West Africa, with interest gaining in the United States and elsewhere.

Potential Health Benefits of Holy Basil Tea
Therapeutic uses of holy basil feature the leaves, stems, and seeds, to brew a herbal tea or tincture, but also to make an essential oil. It is a common herb in Chinese and Ayurvedic medicine, known to help skin, respiratory, gastrointestinal, and joint conditions.
Research and studies on this herb have begun to support several of the traditional medicinal uses of holy basil. Potential health benefits of holy basil include the following:
Reduction of Respiratory Issues
Holy basil contains bioactive compounds like eugenol, camphene, cineole, and camphor that may help to open your airways and improve breathing. These compounds may also have antimicrobial and antiviral activities that help reduce the duration of common cold and flu symptoms.
Stress and Anxiety Regulation
Known as an adaptogen herb, holy basil has several components that may help reduce mental stress that comes from physical, environmental, and emotional triggers. Holy basil may have a direct influence on cortisol hormones that circulate in the blood, helping to balance the adrenal glands and reduce excess cortisol.
Improved Dental Health
Components like ursolic acid, rosmarinic acid, and eugenol work to reduce inflammation. Since they also have antibacterial and antioxidant properties, these compounds found in holy basil may reduce plaque buildup on your teeth and lower your risk of developing other periodontal conditions.
Potential Risks of Holy Basil Tea
While holy basil and holy basil tea have several potential benefits, it may affect some people negatively. Consult with your doctor before adding holy basil tea to your daily routine.
Here are some of the potential risks:
Pregnancy and Breastfeeding Concerns
It isn’t fully known if drinking holy basil tea while pregnant or breastfeeding could result in health risks. To avoid any possible negative effects, don't take the herb in any form if you're pregnant or nursing your child.
Decreased Fertility and Sperm Mobility
If you and your partner are trying to conceive, it’s best to avoid holy basil tea. Effects are inconclusive as to whether this herb affects sperm count and mobility.
If you're taking blood-thinning medication, avoid taking holy basil tea because it may result in bruising or bleeding. Blood-thinners are medications such as aspirin, heparin, and more. You may be more familiar with names like Coumadin, Fragmin, Plavix, Lovenox, or Ticlid.
Since the aromatic herb can slow your blood's ability to clot normally, it’s best to avoid drinking holy basil tea before surgery.
