    What does it do?

    Supports Bowel Movement

    There are few things in life more frustrating than having the sensation of really needing to go to the bathroom but unsuccessfully evacuating the bowels. If you can relate, you're not alone.

    If you want to safely and easily move the bowels, Constipass™ may help. This all-natural traditional Chinese medicine supplement contains six herbs that address the imbalances which have led to infrequent bowel movements.

    Customers who have had positive outcomes with Constipass™ love how easy it is, simply by taking a handful of tablets instead of having to pursue more inconvenient and uncomfortable solutions.

    Signature TCM formula Moistens the Intestines

    According to TCM theory, hardness in bowel movements may be caused by various reasons, such as excess heat or deficiency. Constipass™ is beneficial for infrequent bowel movements caused by excess heat in the intestines and stomach, signs of which include dry stool, along with heat sensation in the body, red face, red tongue, dry mouth with bad breath, and dark urine.

    In general, heat dries out the fluids that are related to digestion. And in order for the body to compensate for the dryness, it removes moisture from the food in the intestines. When excess fire and heat dries out fluids in the intestines, stools become harder and more difficult to pass.

    Constipass™ works by building back up the fluids that have dried out and become deficient.

    Constipass™ does not work immediately; take it as directed for 2-3 weeks to notice the benefits, though you may notice positive outcomes sooner.

    How does Constipass™ work?

    The following three herbs have the primary action of moistening the intestines and unblocking the bowels: Tao Ren (Peach kernel), Huo Ma Ren (Hemp seeds), and He Shou Wu (Fleeceflower Root).

    The main action of Da Huang (Rhubarb Root and Rhizome) is to drain heat, resolving intestinal fire and abdominal fullness, while Dang Gui (Chinese Angelica Root) tonifies the Blood. Dang Gui is also an efficacious TCM herb that helps move the bowels because of its intestine-moistening properties.

    And finally, the last herb in Constipass™ is Qiang Huo (Notopterygium Root), which chiefly dispels wind.

    Constipass™ (Tong Chang Pian) is rated 4.7 out of 5 by 15.
    Rated 5 out of 5 by from Really Great! It Works. I take this at the same time I take a medication that causes constipation (I take 7 to 10 tablets). This herbal formula completely counteracts the constipation tendency (sorry if this is TMI) and neutralizes the situation. I also drink a tea blend of organic rose petals and damiana with it which provides a gentle and natural laxative effect. This is a wonderful product and it really works! This company has really FAST and reliable shipping too! I am a big fan of nature and not synthetic medications. I must also remember to drink A LOT of water while taking this formula. : )

    Rated 5 out of 5 by from If your plumbing is backed up, this will fix it. I bought Constipass for a few family members who regularly have constipation issues and this did the trick. One family member used the recommended dose and her problem was fixed within a few hours. The recommended dose did not work for another family member, however. My Chinese Herbalism teachers suggested the following: early afternoon, early evening take 12 pills, if there’s not a bowel movement by morning take 12 more pills. This worked for him. Constipation is a big problem for a lot of people and the gentle effectiveness of Constipass is a blessing for them. Thank you ActiveHerb.

    Rated 5 out of 5 by from Very effective I had a 3 or 4 month bout of intestinal illness after eating a raw or undercooked meal, and a side effect of the illness was bad constipation. This product saved me from misery during that time period. I took less than the recommended dose, no more than 4 pills at once and only once or twice a day. When I started feeling completely better after 4 months, I weaned myself off of the Constipass pills over a couple of weeks. I'm totally back to normal health. I can't recommend these pills highly enough!

    Rated 5 out of 5 by from Amazing and Gentle This is an amazing product that is easy to use and easy to control. Fluctuating the dosage brings about subttle differences in the effectiveness of this product. Highly recommended! 10 out of 10!

    Rated 5 out of 5 by from Gentle, high quality product I use this more regularly than I would like due to IBS. It is far more gentle than even natural laxatives and it works in a reasonable, not hyper-speedy, way. I recommend this for people with IBS or food intolerances who need some help once in a while!

    Rated 5 out of 5 by from Excellent product My husband and myself are very satisfied with Constipass. We take 7 to 10 at a time and sometimes it requires another dose but it always works. The best feature of this product is that we never experienced cramps or any other discomfort.

    Rated 3 out of 5 by from More of a stool softener This product does not work to go to the bathroom overnight or even the next day. It is so much like a stool softener nothing more. I do not like the return policy making it not worth the money to return.
