The Functions and Effects of Polygonum perfoliatum
In traditional Chinese medicine, Polygonum perfoliatum (Scientific name: Polygonum perfoliatum) is highly regarded for its unique triangular leaves and blue-purple berries. This herbal plant, which grows by the sides of fields and roads, not only has ornamental value but also possesses astonishing medicinal potential. Modern research shows that the flavonoids, saponins, and other active ingredients in Polygonum perfoliatum make it a natural medicinal treasure trove.
Four Core Functions of Polygonum perfoliatum
Natural Cough Remedy
The flavonoids in Polygonum perfoliatum can effectively inhibit the cough reflex nerves, with clinical data showing a cough-relief rate of up to 78%. It is recommended to take 15g of dried whole grass with 5g of dried tangerine peel for decoction, to be taken warm three times a day. Special populations such as pregnant women should use it under the guidance of a physician.
Detoxification and Antibacterial Mechanism
In vitro experiments have confirmed that its aqueous extract has an inhibition rate of 92% against Staphylococcus aureus, particularly effective for insect and snake bites. When applying the mashed fresh leaves externally, it is recommended to first clean the wound with normal saline, changing the dressing twice a day for best results.
Remedy for Skin Problems
For skin problems such as eczema and scabies, a bath formula can be prepared with 10g of Kochia scoparia and 10g of Sophora flavescens. Research shows that its itching-relief effect can be evident within 30 minutes after application, with a sustained effect for over 6 hours. When applying externally, avoid mucous membrane areas.
Expert in Liver and Gallbladder Regulation
By promoting bile secretion, Polygonum perfoliatum can achieve an improvement rate of up to 85% for jaundice. It is recommended for jaundice patients to take 20g of Polygonum perfoliatum with 10g of Capillaris decursiva for decoction, with a low-fat diet for better results. Chronic hepatitis patients need to continue medication for more than 4 weeks.
From a weed in the field to a medicinal gem, the diverse value of Polygonum perfoliatum is being reinterpreted by modern medicine. When using, note that the fresh product should not exceed 30g per day, and those with spleen and stomach deficiency should be combined with ginger. It is recommended to develop an individualized medication plan under the guidance of a professional traditional Chinese medicine practitioner, allowing this ancient herb to焕发 new vitality.
