The recipe here is slightly complex! Take one chatak each of the leaves of neem, sambhar salt (a salt prepared from the sambhar lake in Rajasthan), dried Cannabis (bhang in Hindi) and young branches of the bamboo. Pound them together, grind and make small tablets out of them.
Place them in a mud pot, close its’ mouth and invert and then keep it in a mass of live coal, for quite some time. Remove the pot after this and when it cools down fully by itself, powder the tablets and store this powder well. The dosage is 1, 1/2 to two rattis. Lick this in the early morning along with honey.
This is said to give relief in breathing difficulties, cough and specially the cough due to kapha, and also in asthmatic troubles.
Taking twenty-five to forty drops of the pure oil from neem seed along with betel leaf is a simple procedure advised in many troubles of coughing and asthma.
