That is excellent! It probably works much better in formula than by itself. The Chinese have centuries of experience developing formulas. On the other hand some of the best ones have remained unchanged for centuries. The main thing is they work and are safe.
I’m lucky! My Doc is a Master! Ran an herbal hospital outside Shanghai for many years before emigrating. I no longer have to take Metformin for Type 2, nor Atenolol for BP. Diet also played a large part. I managed to lose(loose!) 50 pounds. I no longer have to walk with a cane. And that bad knee was fixed by the herbs 5 years before I lost the extra weight, although I’m sure the weight “loose” helps in the looong run. But, ya gotta find a good, experienced herbalist, preferably from the Mainland, not Taiwan or Hong Kong.
