    What does it do?

    Helps you enjoy easier elimination!

    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. Over 60 million people in North America meet the diagnostic criteria for chronic constipation.

    Perhaps you’ve previously tried western approaches to treating constipation, such as laxatives. But laxatives can negatively alter electrolyte balance and cause dehydration. And with repeated use, laxatives may actually cause 'reflex constipation.'

    All-natural herbs safely and gently help move the bowels with ease

    If you want to safely and easily conquer constipation, Constipass™ may help. This all-natural traditional Chinese medicine supplement contains six herbs that address the imbalances which have led to your elimination difficulties.

    Customers who have had positive outcomes with Constipass™ love how easy and cost-effective it is to relieve constipation, simply by taking a handful of tablets instead of having to pursue more inconvenient and uncomfortable solutions such as enemas and cleansing teas that cause rapid and unpredictable bowel evacuations.

    Signature TCM formula moistens the intestines and restores digestive fluids

    According to TCM theory, constipation may be caused by various reasons, such as excess heat or deficiency. Constipass™ is especially beneficial for constipation 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, constipation 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 like a laxative; 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.
