To prepare this natural remedy yourself: Use two parts cat's claw and one part each for the remaining plants shown in the list above. To make a small amount... "1 part" could be one tablespoon (you'd have 8 tablespoons of the blended herbal formula). For larger amounts, use "1 part" as one ounce or one cup or one pound. Combine all the herbs together well. The herbal mixture can then be stuffed into capsules or brewed into tea, stirred into juice or other liquid, or taken however you'd like.

Suggested Use: Take 2-3 capsules three times daily on an empty stomach.

Contraindications:
  • Not to be used during pregnancy or while breast-feeding.
  • This product should not be used with medications intended to suppress the immune system.
Drug Interactions: May potentiate blood thinning medications such as Warfarin. May reduce the effect of immune suppressants.

Other Practitioner Observations:
  • Several plants in this formula contain a low concentration of coumarin which has an anticoagulant effect. People with blood disorders such as hemophilia, or those on blood thinning medications should be monitored closely.
  • Cat's claw and jurubeba have been documented to have an antifertility effect. Those seeking to become pregnant or those undergoing treatment for infertility should not use this formula.

Cat's Claw (Uncaria tomentosa)
Cat's claw has been traditionally used as a bowel cleanser and anti-inflammatory for Crohn's, colitis, diverticulitis, irritable bowel syndrome (IBS), and other bowel problems; as well as for stomach ulcers and ulcerative colitis and as an ulcer preventative, stomach and bowel protector. It has demonstrated anti-inflammatory actions in the studies cited below.

Boldo (Peumus boldus)
Boldo's main active chemical, boldine, has shown in animal studies to provide anti-inflammatory and antispasmodic action, as well as the ability to protect against colon damage and inflammation in induced colitis and colon inflammation. A recent human study demonstrated that boldo relaxes smooth muscle tissue and prolongs intestinal transit.

Macela (Achyrocline satureoides, Egletes viscosa)
Macela has been reported in several animal studies with mice and rats, to possess analgesic, anti-inflammatory, and smooth-muscle (gastrointestinal) relaxant properties internally without toxicity, in addition to anti-inflammatory and analgesic actions externally. This may explain why macela has long been used effectively for many types of pain, gastrointestinal difficulties, menstrual cramps, and asthma.

Simarouba (Simarouba amara)
The Merck Institute reported that simarouba was 91.8% effective against intestinal amebas in humans in a 1944 study and, in 1962, other researchers found that simarouba showed active anti-amebic activities in humans. In the 1990s scientists again documented simarouba's ability to kill the most common dysentery-causing organism, Entamoeba histolytica, as well as two diarrhea-causing bacteria, Salmonella and Shigella.

Jurubeba (Solanum paniculatum)
Jurubeba has been reported with antiulcer activity. In animal studies it was reported to inhibit gastric acid secretion induced by stress and various chemical agents, as well as prevented gastric lesions from developing. Additionally it was reported to inhibit gastric acid secretion in mice with the ulcer-causing bacteria H. pylori. Researchers summarized: "Collectively, the results validate folk use of Solanum paniculatum plant to treat gastric disorders."
