Cures a fever: Tulsi has very potent germicidal, fungicidal, anti-bacterial and anti-biotic properties that are great for resolving fevers. It has the potential to cure any fever right from those caused due to common infections to those caused due to malaria as well. In ayurveda, it is strongly advised that a person suffering from fever should have a decoction made of tulsi leaves. In case of a fever boil a few leaves of tulsi with powdered cardamom in half a litre of water( The proportion of tulsi to cardamom powder should be in the ratio 1:0.3). Let it reduce to half its total volume. Mix this decoction with sugar and milk. Sip every two to three hours. This remedy is especially good for children.
