    ActiveHerb extract granules vs. herb powder
     Potency. 1 g extract granules is equal to 5 g herb powder.
     Purity. Our extract granules only retain the active ingredients extracted from the herb while the herb residue that counts for most of the dry weight is discarded. For herb powders, everything of the herb is consumed.

    Rated 4 out of 5 by from Give it a try. Saw the Dr Oz show and thought what the heck. I will only lose $25 if it doesnt work. Guess what? It does help. Doesnt take away all the pain but takes it down a couple of notches without drugs or side effects so that is a plus for me. I only took it twice a day and one scoop each time. I will continue using it. It takes the edge off and I can live with that.

    Rated 4 out of 5 by from Really works! After seeing this on Dr. Oz show, I thought I would try. Glad that I did. I have had chronic pain for over 20 years. I have tried physical therapy, prescription pain meds, even injections into my back. Since taking this product, I am able to do things without the side affects of drugs, etc.

    Rated 5 out of 5 by from Good Results This product replaced my Percocet for my neck/spinal pain from 2 of my neck discs which are hitting my spinal cord causing great pain in my left arm. I am talking a few different pain medications, one of which is Percocet. This Yan Hu Suo replaced it and gives me some relief.

    Rated 5 out of 5 by from Amazing pain relief! I have used this product for 3 months now and it is amazing. I have arthritic knee, and shoulders and back. Before only opium class pain medicine would work effectively. Now after 30 years, this product has taken me off those kinds of medicines and I am truly relieved.

    Rated 5 out of 5 by from Awesome! My husband and I started taking Corydalis two months ago for our pain. He has had 5 back surgeries and for 19years has had to take prescription for it just to get through the day. Constant pain, And I have bulging disc, Spurs , arthritis and sciatic nerve. Corydalis lets us do things without centering on the pain. It's there but the neurons in the brain aren't constantly reminding you. Anyway I get relief from my pain and relief not having to hear my husband moan all day over his back. Which I know he is hurt but 19 yrs of hearing it makes one crankyLol try it it works mix it with tea and honey in the morning, and if you've put in a hard day take it at night before bed. Two small scoops once or twice a day! Much better than prescription drugs any day!

    Rated 1 out of 5 by from Does it Work? I have read that this product works well for some and not so good for others. I am one of "those others". I have taken this product for five days and I honestly haven't felt my pain lessen any. Too bad, too, I was really hoping it would work. I do have to warn you though, it is quite nasty tasting and you kind of have to hold your nose to drink it.

    I am the same person who asked the last question. I forgot to mention that the articles also recommended 3 to 9 grams of the Corydalis grandules with the 5:1 which is the same as your Corydalis.

    Asked by: Sincerely2
    Depending on an individual's specific condition, a practitioner may recommend a specific dosage. In general, herb products are safe within a range of prescribed amount. You may consult with a professional or start with a lower dose of 1-2 grams.

    I have been reading about Corydalis grandules and the articles say to take 3 to 9 grams per day. I noticed that the Active Herb Corydalis says to take 1 to 2 grams per day. Can you explain why you recommend less grams? Thank you for your help.

    Asked by: Sincerely2
    Thank you for your question. Our extracts are 5 to 1 concentrated so 1 gram of granules is equivalent to 5 grams of raw herb. Our suggested dosage of 1 to 2 grams therefore is equivalent to 5 to 10 grams of raw herbs.

    I am a little confused on the corydalis. I have fibromyalgia, bone pain, migraines, I am fatigued most of the time, I stay hot most of the time and sweat, but which would be the best Corydalis Rhizome or Corydalis Relax ? I have depression and anxiety t

    Asked by: mktyler
    Corydalis Relaxe tablets contain additional herbs that enhance the action of Corydalis rhizome. Such a combination is the preferred way of using Corydalis in Chinese medicine. Thank you.
