HH 2 Capsule is a double strength version of HH Capsule


Constituent Herb:

Houttuyniae herba (HH) is the leaf of Houttuynia cordata Thunb. (Saururaceae). (The Great Dictionary of Chinese Materia Medica 1988)


The chief anti-bacterial compound of H. cordata is decanoyl acetaldehyde. (Liu YL et al., 1978, Kosuge T.1975, Isogai Y.,1953) The English name is new sodium houttuyfonate.

HH has been effectively used to prevent and treat leptospirosis, an infectious disease caused by spirochetes. (Leptospirosis Research Unit, 1972)

HH has shown significant activity against many bacteria and fungi. In vitro tests showed that it can markedly inhibit gram-positive and gram-negative bacteria. The most sensitive organisms were Staphylococcus aureus and its penicillin-resistant strains, Diplococcus pneumoniae, Alpha streptococcus, Hemophilus influenzae. Neisseria catarrhalis, and Salmonella typhi. Escherichia coli, Pseudomonas aeruginosa, and Shigella dysenteriae showed marginal sensitivity. (Leptospirosis Research Unit, 1971, 1972,, Yang HC et al., 1953, Jiangxi Medical Information 1972)

HH also inhibits Candida albicans, Cryptococcus neoformans, Sporotruichum, Aspergillus, Chromomycosis, Epidermophyton rubrum, Tinea imbricata, Microsporum gypseum, Microsporum ferrugineum, and sharkskin fungus.  HH has shown inhibitory actions against Diplococcus pneumoniae, Salmonella typhi, Staphylococcus aureus, Escherichia coli and Sporotrichum in vitro. It has also strong inhibitory actions against Mycobacterium tuberculosis both in vitro and in vivo. HH injection to tuberculin mice at 1mg/mouse prolonged survival by 62 days; the therapeutic effect was enhanced when the agent was mixed with the animal feed. (Kosuge T et al., 1952,1956, Materia Medica Section, 1978)

HH is also immune-enhancing, edema-alleviating, and anti-inflammatory, all of which are of great importance in the treatment of infectious diseases. (Bronchitis Unit, 1973, Medical Laboratory, 1975)

Pharmacokinetic studies found that its half-life is 3.5 hours in the rat gastrointestinal tract. It was quickly distributed, first in the lungs, next in the heart, liver, and kidneys, and minimally in the serum. (Materia Medica Unit, 1976)

HH has very low toxicity. The LD50 in mice was 1.6± 0.81 g/kg. Intravenous infusion of 38 or 47 mg/kg to dogs did not cause any abnormalities in the heart, lungs, liver, kidneys, spleen, stomach, or intestines.( Jiangxi College of TCM, 1977)
