Agreed what you write about the source. I would also consider working with someone who is knowledgeable about Chinese herbs. This is fascinating information. One wonders why it may lead to "treatments"? Is not taking the herb good enough? Or is someone missing out on profiting at the expense of sick individuals? I know I would look to the herb, not something synthesized in a laboratory. We wonder why healthcare (sickcare) is so costly; this is one component of that large expense.
Almost all of us long for peace and freedom; but very few of us have much enthusiasm for the thoughts, feelings, and actions that make for peace and freedom. - Aldous Huxley
Was the government to prescribe to us our medicine and diet, our bodies would be in such keeping as our souls are now. - Thomas Jefferson
