I don't understand this at all. Bitterness in a substance triggers bronchodilation by taste buds. The principle is used in the case of asthmatics.
Bitterness is created as a warning by poisonous plants. Which are the poisonous herbs in this prep?
Here's the question: if it creates a swelling in the throat, then why doesn't it create similar swelling all the way down thru the smooth muscle of the digestive tract? This isn't making one bit of sense to me. I use the formula daily in caps.
