Mulethi is commonly known as licorice. It is an herbal supplement which treats a lot of medical conditions. Mulethi has an enticing scent, this comes from a variable and complex combination of compounds out of which anethole makes up 3% of the entire plant. Most of the sweetness comes from a substance called glycyrrhizin, it is generally 30 to 50 times sweeter than sugar. Isoflavane glabridin is found in the roots of the licorice.
