Neem: The Most Powerful Anti Viral Immunity Boosting Herb

Medical Reviewer: Dr Surabhi Rawat

The neem tree, scientifically known as Azadirachta Indica is an ancient Indian medicinal tree whose references appear in numerous Hindu scriptures as old as 5000 BC. It is described in many Ayurvedic texts as ‘Nimba’ (giver of good health) and ‘Sarva roga nivarini’ (the universal healer of all ailments).

Neem is said to originate on earth after the Devas threw a few drops of Amrita or elixir of immortality on Earth. It is believed that neem is an incarnation of the Mother Goddess and is thus called Neemari Devi.

The neem plant is called Arista in Sanskrit which means perfect and imperishable. It is referred to as the Indian lilac in English.

Thirumular Thirumantiram-Ennayiram, an ancient Tamil text makes a reference to this tree. It writes:

“Oh, Damsel of flowing tresses and slender forehead!
Hear you a miracle this!
In this water hidden in the body
Mix pepper, alma, turmeric and neem
Soft will your body be;
And dark thin hair on the head”

The great ancient Indian Ayurveda practitioners – Charaka and Sushruta also write about the healing properties of neem in their books.
