What is Holy Basil?
Holy Basil, also known as Tulsi, is one of the most sacred herbs in Ayurvedic medicine. Revered for over 3,000 years, it's celebrated as an "adaptogen" β a natural compound that helps the body restore balance and cope with physical, mental, and emotional stress. Traditionally used to promote longevity and vitality, Tulsi supports the immune system, hormone balance, and mental clarity, making it a go-to herb for those feeling burnt out, anxious, or constantly "on edge." Today, it's widely consumed as Holy Basil tea, tincture, or capsule β prized for its ability to reduce anxiety, regulate blood sugar, and protect against environmental toxins.

How to Use Holy Basil
Holy Basil Tea (Daily Stress Relief)
Steep 2-3 teaspoons dried tulsi leaves in hot water for 5-10 minutes. Drink 1-2 cups daily, preferably in morning and evening, for consistent adaptogenic support.
