Tulsi scientific name (Ocimum sanctum) is one of the most sacred plants in India and is often kept in courtyards and houses for its purifying and beneficial influence on its surroundings.

Tulsi tea helps prevent certain respiratory illnesses ranging from cold and cough to bronchitis and asthma. It has immunomodulatory (helps to enhance immunity), antitussive (helps relieving cough) and expectorant (helps in expelling out the phlegm) properties that provide relief in the respiratory system. A great way to consume tulsi is to make a tea. Boil a few fresh holy basil leaves powder with one cup of water, and steep for five minutes. You can also add some fresh mint leaves and lemon to it. Now, drain and drink this tea to take full advantage of all of these benefits.
