Get well and stay well
It works. If you feel a cold coming on, pop a few of these and you will often (not always) beat it back completely. If you do get the cold, these mitigate the effects dramatically. Wonderful product. Western medicine's toxic pharma products in your local drug store with their antihistamines and cough suppressants are no match for yin chiao. Tastes pretty bad but who cares if you don't get sick!  A bargain.
