A.      Herbal Composition:

Smilax glabra root, Baikal skullcap root (Scutellariae Radix), Chinese goldhread rhizome (Coptis chinensis Franch Radix), Dandelion entire plant, Japanese honeysuckle flower, Polygoni cuspidate rhizome (Polygoni Cuspidati Rhizoma), and Chinese licorice root.

B.       Clinical Pharmacology:

The phytopharmacology of the major ingredients of this formula: Smilax glabra (SG), Scute, Coptis, and Licorice are presented here.

1.        Smilax glabra root has found to have anti-spirochetal effects and been successfully used for treating syphilis and leptospirosis. SG has been studied as a preventative treatment for leptospirosis. In 2,000 people tested, the incident rate of a pre-treated group compared with a control group was 1:5.58, a statistically significant result, demonstrating that taking SG can successfully prevent leptospirosis. When used to treat syphilis, SG combined with other Chinese herbs can achieve a greater than 90 percent sero-convert rate back to negative. Even for the late stages of syphilis, the cure rate is above 50 percent. [1]

2.        Scutellariae Radix has been tested and found to have suppressive effects on the spirochete of leptospirosis, and have been effectively used to treat leptospirosis in China. [2]

3.        Coptis’ major chemical ingredient is umbellatine. Pharmacological studies found it has a wide anti-infectious spectrum. It can strongly suppress Staphylococcus aureus, Streptococcus, pneumococcus, Vibrio comma, anthrax bacillus, and Bacillus dysenteriae.  It can also suppress hay bacillus, pneumobacillus, Bacillus diphtheriae, Bordetella pertussis, Brucellaceae, and Mycobacterium tuberculosis.  Its potency is roughly equal to or stronger than that of sulfanilamide and slightly weaker than that of streptomycin and chloramphenicol. It has strong bacteriocidal effects on spirochete. It also has anti-viral effects and can suppress the following viruses in vitro tests: influenza viruses, Newcastle disease virus. It can also suppress other pathogens, such as Ameba, Chlamydi trachomatis, trichomonad, and Leptospira. Its toxicity is low and is a safe herbal remedy, with virtually no side effects. Long-term use has not caused any adverse reactions and no accumulative toxicity.  LD50 for rats is 205mg/kg. [3,4,5,6,7,8,9]

4.         Licorice root has anti-allergic, anti-inflammatory, and detoxifying activities are all important for its use in treating chronic Lyme disease.  Its anti-allergic and anti-inflammatory activities resemble the activities of glucocorticoid since this herb maintains the level of active corticoid in the blood and increases endogenous corticoid by inhibiting the deactivation of glucocorticoid in the liver. Further, it promotes the regeneration of inflammatory tissue in contrast with glucocorticoid, which inhibits the regeneration. It also inhibits the release of histamine from mast cell thus reduce the inflammation. [10]

Package: One capsule contains 750 mg of the extract of this formula. One bottle contains 45 capsules.

      Dosage:  Take one capsule three times a day, before meals.
