Weights & Measures
This is a very strong formula and should only be used in suitable cases for a short period of time without modification. If the Yang is weak (such as in the elderly and weak), add Yang tonic mediicnes. Because this formula is very Warm and strong to release the Exterior (ie. promote sweating), it can deplete the body and plunder the Yin and Yang.
