Duckweed, mostly found in ponds.
In many parts of the countryside, it is common for people to salvage it from ponds and feed it as fodder for poultry.
The history of its use in medicine can be traced back thousands of years. For example, the earliest monograph on Chinese medicine, "Shennong's Materia Medica", has recorded this good medicine, and said that it can relieve the evidence of 'hot and itchy body, drunkenness and thirst'.
The medicinal value of this substance has also been mentioned in the herbal classics of the past dynasties, and as for its specific use, it can be summarized as follows.
1. Wind-heat symptoms
Duckweed is born when it encounters water, and it has a natural cold, so it is believed in traditional Chinese medicine that it has a cold breath when used in medicine, and its smell is pungent, so it can play a certain role in relieving the surface of pungent coolness.
It is recorded in some folk remedies that if you encounter the disease of wind and heat, you can fry duckweed in water for several bowls, take a little while it is hot, and then soak the towel into the remaining liquid hot compress on the chest and back, palms and feet, which can play the effect of heat dissipation.
In traditional Chinese medicine, duckweed is often used in combination with ephedra, cinnamon branches, forsythia, Qianghuo, Poria cocos, Angelica dahurica, cicada molt, kudzu root, nepeta, etc., which is also effective in alleviating wind-heat diseases.
2. **Sores
Traditional Chinese medicine believes that duckweed floats on the surface of the water and has the power to penetrate the surface of the skin, so its pungent and cool air can also travel to the surface of the skin, so as to alleviate the symptoms of sores on the surface.
For skin rubella, itching and pain, as well as sores on the surface, redness, swelling and pain, etc., the ancients often used to directly use this decoction to bathe, or rinse**, which can be effective.
In traditional Chinese medicine, duckweed is often used in combination with burdock seeds, mint leaves, cicada molting, nepeta spikes, peony skin, white fresh skin, etc., which is also used to alleviate common skin sores and measles.
3. It is not good to urinate in the air
This thing is pungent and dissipated, cold and downward, it can play the function of promoting lung qi, and can play the effect of benefiting the waterway, and it can also be used for some common waterways that are not smooth and unfavorable to urinate.
In some folk places, people will salvage some duckweed in the summer, and then dry it for later use. If there is a time when urination is unfavorable and scorched edema, it can be directly ground into a fine powder to drink, which can play a role in urination.
In traditional Chinese medicine, it is often used in combination with medicinal materials such as ephedra, winter melon skin, Zhu Ling, Ze Yuan, etc., and its role in regulating water channels is also very obvious.
4. The upper coke is hot
The texture of duckweed is frivolous, its medicinal effect is easy to go to the coke, and its smell is cold and settled, so it can also play a role in inducing heat downward. Therefore, for the case of real heat evidence on the coke, it can also be used as a medicine to obtain good results.
For example, the heat on the coke is heavier, and then accompanied by frequent epistaxis, sores on the mouth and tongue, dry throat, and polydipsia.
In traditional Chinese medicine, when dealing with the above discomforts, they often choose to use them together with cork, indigo, grass root, reed root, and arborvitae leaves, which are also effective.
