Yin Chiao Plus is best used at the first sign or in the early stage of a common cold of flu. It is best if taken in the first 24-48 hours, with symptoms of a sore throat, stuffy nose, heavy head, aching neck and slight fever. Yin Chiao is not appropriate once the illness enters the lungs and cough is present.
Adding Echinacea at 1tsp of the liquid 3 times a day is beneficial.
