The medicinal use of Viola yedoensis was first recorded in "Qianjin Prescription" written by Sun Simiao, the "medicine king". Sun Simiao believed that Viola yedoensis had remarkable effects of clearing away heat and toxic materials, curing sores and eliminating carbuncle.
After hundreds of years of experience, Li Shizhen affirmed the detoxification and heat-clearing effect of Viola yedoensis in Compendium of Materia Medica, and thought that Viola yedoensis could eliminate "all boils, furuncles, carbuncles and malignant sores" when used as medicine.
Of course, Li Shizhen's statement may have some exaggerated elements, but according to modern medical research, some chemical components contained in Viola yedoensis do have certain effects in helping people to resist bacteria and inflammation and regulating human immune function, which shows that the traditional Chinese medicine in these rural areas can stand the test of time and science.
In the theory of modern Chinese medicine, people think that Viola yedoensis has bitter and pungent taste, and its medicinal properties are cold and cool, and it has excellent effects of "clearing away heat and toxic materials, cooling blood and reducing swelling". Among some folk remedies, Viola yedoensis also has many wonderful uses!
First, the magical use of Viola yedoensis "detoxification and detumescence"
The medicinal property of Viola yedoensis is bitter and cold, which has a good relieving effect on the internal and external sores and carbuncles of the skin caused by heat toxin in the body. Moreover, in ancient times, people also called Viola yedoensis "a universal medicine for eliminating carbuncle and detoxification", which has good effects on all kinds of common skin sores and swelling.
For example, when there is a red lump on our skin, or a sore on our skin, we can dig some fresh Viola yedoensis directly, then mash it until the juice flows out, and then apply it externally to reduce swelling and treat the sore.
Sometimes there will be some nameless induration inside our skin, which will be painful or painless when pressed by hand. At this time, boiling water with some roots of Viola yedoensis can also be effectively relieved.
Second, the magical function of Viola yedoensis in removing "heat accumulated in viscera"
If Viola yedoensis is used internally, it also has a good effect on clearing away the heat, toxin and fire evil accumulated in the viscera. In ancient times, viola yedoensis was commonly used as a good medicine when people had symptoms of heat toxin in their bodies.
For example, the accumulation of pathogenic heat in the lung, sore throat and throat inflammation caused by upper inflammation to the throat, etc., making tea with Viola yedoensis and honeysuckle has obvious effects of clearing away heat and relieving sore throat. For the damp heat accumulated in the liver and gallbladder, some folk places use Viola yedoensis and honey decoction to relieve it.
In addition, the coldness of Viola yedoensis can also enter the blood, so when the evil of heat toxin invades the blood, or when the blood is warm and dry, and the blood is hot and nosebleeds, making tea with Viola yedoensis can also cool the blood.
Third, the magical use of Viola yedoensis to get rid of exogenous heat evil
Viola yedoensis can not only help people to clear away the above-mentioned symptoms of excess heat, but also be effective for some febrile diseases caused by exogenous factors.
For example, the most common disease of exogenous wind-heat in life, that is, we often say that wind-heat colds and so on, can play the role of dispersing wind-heat by taking Viola yedoensis as medicine.
For this kind of situation, the effect of using Viola yedoensis alone is generally not very significant, so it is often used in Chinese medicine with chrysanthemum, dandelion, honeysuckle and isatis root, which can effectively alleviate the evil of wind-heat and eliminate the symptoms of sore throat, dry mouth, fever and weakness accompanied by wind-heat cold.
