The other brand was rated 4.7 stars out of 9 reviews here, so I thought I would give it a shot. It was so bad it quickly brought all of my symptoms back that it was relieving within days, and I am so glad I had made sure I had some of these extra lying around to take while I wait on another order from iHerb. I have tried another brand of Cordyceps that worked really well, and it actually cured nerve damage in my neck and shoulder and more years ago. It's even more expensive than Dragon Herbs, and quite potent, but still not as good as the Cordyceps from Dragon Herbs. I am taking them now to deal with some symptoms from Lyme disease and other co-infections, and if it helps with that it will help most anything. Cordyceps mushrooms can do some pretty amazing things, and these are so potent I don't even need to take the maximum dose with these like I have to with every other brand.
