Houttuynia cordata

Houttuynia root can improve the phagocytic ability of WBC and increase blood cell properdin. When treating chronic bronchitis, the production of houttuynia root can significantly enhance the patient's WBC's phagocytic ability of Staphylococcus aureus and significantly increase blood cell properdin. Rabbits were given 8 mg of houttuynia cordata intramuscular injection daily. After 3 days of continuous administration, the level of properdin in blood cells also increased significantly. Houttuynia cordata root can enhance the body's immune ability and has important practical significance for the treatment of infectious diseases.

Antibacterial effect

A light yellow oily substance was extracted from the root of Houttuynia cordata, which has an inhibitory effect on various microbial species (especially yeast and mold), and has a significant inhibitory effect on hemolytic streptococci, Staphylococcus aureus, Streptococcus influenzae, catarrhal Gram-negative bacilli, and Streptococcus pneumoniae. It is also effective against Escherichia coli, Shigella dysenteriae, and Salmonella typhi. The synthetic decanyl hydrobromide and sodium bisulfite additive is called synthesized houttuynia cordata. The resulting sodium dodecyl bromide and sodium bisulfite adjuvant is called neohyaluronic acid, which has a significant inhibitory effect on a variety of bacteria in in vitro experiments: the MIC for Staphylococcus aureus and penicillin-resistant Staphylococcus aureus is 62.5-80Mcg/ml, and for Streptococcus influenzae is 1.25mg/ml. The concentration for Mycobacterium tuberculosis H37RY strain in Purbeck liquid culture medium is 16mcg/ml. On the improved Tongzhou Wan's semi-solid culture medium, it is 25mcg/ml, and its potassium salt is 12.5mcg/ml.

Antiviral therapeutic efficacy

Using engineered embryonic kidney primary single-sided squamous epithelial cell tissue shaping, Houttuynia root decoction (l:10) had an inhibitory effect on the Asian influenza A Jingke 68-1 strain, and could slow down the growth and development of abandoned virus-infected ECHO11. Use alcohol to obtain several fixed oil parts. Among them, houttuynia cordata III has a protective effect on mice infected with influenza virus, but has no significant effect on EMC and HSVⅡ. The compound that produces houttuynia cordata also has a strong antiviral therapeutic effect. Houttuynia cordata root extract (4g crude drug/ml) has a significant preventive and protective effect on mice infected with the common cold virus. However, it has no significant protective effect against encephalomyocarditis virus infection and herpes virus type Ⅱ infection. It was also confirmed that the anti-influenza virus components of Houttuynia cordata root are not in the volatile oil part, but in the non-volatile organic matter.

Good for urination

Perfusing toad kidneys or frog webs with Houttuynia cordata root extract can dilate capillaries, increase blood volume and urine metabolism, and thus facilitate urination. Its effect may be caused by organic compounds, and potassium only plays an additional role in enhancing diuresis. When it works directly, it can weaken the activity of Neisseria meningitidis, kill it, or destroy it, and it can also delay the onset of disease in guinea pigs artificially infected with Neisseria meningitidis.
