The “Ba Zhi San “protocol not only heals the acute condition, but also helps the anus-specific blood circulation to improve. Our data suggests less than a 2% chance that these problems will reoccur after the treatment. Under the terms of the guaranty, if there is reoccurrence, however rare, re-treatment will be offered if the primary disease comes back within 5 years of the initial treatment.

Additional compounds are sometimes used where the patient is in a more advanced state of illness, and there is a need to first remove infection and putrefaction before full healing can begin. The core anti-hemorrhoidal ingredients in the compound actually shut off the blood supply to the affected vein – cutting off the life-blood of the hemorrhoid, in effect – while also encouraging the body to remove water from the affected tissues.

Tested and recognized by medical experts, and approved by the Executive Health Department of the Chinese government, the unique “Ba Zhi San” protocol created by Dr. Chen can be applied as a 100% external Chinese herbal remedy for treating virtually any type of hemorrhoid.

Our “Ba Zhi San ” formula quickly stops the bleeding, and controls the pain from hemorrhoids fissure and fistula. Normally, the patients will see results during the first three days, for example: level 2-3 hemorrhoids will not emerge from the side of the anus after a bowel movement anymore, because the hemorrhoids are shrinking, and they will actually fall off in 5-7 days. If the patient is bleeding, this should stop within 3 days.

The efficacy of “Ba Zhi San,” professionally applied to cases of Fistula and/or Anal Abscess, is based on a proprietary herbal formula which cleans the area, without irritation to skin, while at the same time encouraging the body to heal. In addition, the proprietary “Ba Zhi San” formulation is re-compounded and personalized to individual patients and conditions, offering a treatment program which, in this way, is very highly customized.

Individual compounding of the “Ba Zhi San ” protocol allows rapid relief of: Fissure pain — quickly healing the fissure, and encouraging the scar tissue to fall off.Inflammation (incl., external hemorrhoids) pain — quickly controls the inflammation. Anal Abscess pain — quickly reduces inflammation while speeding up local circulation, so patients usually feel better within 20mins of the first application. Anal thrombosis pain — speeds up circulation in the area of the thrombosis, patient usually feels better the first day of the protocol.

“Ba Zhi San “is able to dissipate moisture and reduce swelling directly on the affected tissues; to encourage the growth of healthy new flesh; to reduce pain; to relieve the underlying causes of the problem; to aid the body in expelling toxins and fight infection. It treats both the root causes and outward symptoms at the same time.

The main ingredients of this “Pull Hemorrhoid Out Powder” (literal translation from the Chinese) also relieve itching and bleeding.
