Hi all. I am struggling with the grand experiment. It seems that so much of herbal medicine is guess work, and a continuous experiment with limited continuity of success. It works often only because I believe it works. Then I find something that seems to be effective, then the herbal source is only 10 % as concentrated as the previous stuff, and therefore not effective. A recent experience with Habanero peppers may best explain some of the variability of products. Seed from one pepper, planted in two gardens in the same general location. Garden A produced peppers with such heat as to burn your face off, tears in the eyes, burning lips and nostrils, with a small nibble. Garden B the peppers could be picked off the plant and eaten whole ,almost as mild as a bell pepper. If the heat, or capsaicin is the "medicine" I certainly want the Garden A peppers. If I have tried the B peppers two or three times, I deem it a failure. If I listen to the claims of sellers, of course they are all effective. So, how long do I continue to test drive the claims of others?, and for how many different ailments, pain, inflammation, colds, runny nose, itchiness etc. etc. Then , how do I measure the quality of product when none has been tested. So I get four different herbal medicines rom a trusted friend. but it was ineffective because I has no colds last year and the medicine was too old by the time I needed it. And I'm not interested in this being my life's work, consuming all my time and resources to find out the correct formula. The thing is, I really would like to have a few trusted effective remedies on the shelf. , without the myriad excuses of why it didn't work.......OK my whining is complete for now, thanks for the ear k
