Because of the unique growth characteristics of Prunella vulgaris, the ancients also described Prunella vulgaris with the phrase "born with pure yang and died in hot summer", which can be said to be very vivid.
The unique growth characteristics also contribute to the unique medicinal properties of Prunella vulgaris. Chinese medicine has already noticed the medicinal value of Prunella vulgaris thousands of years ago.
For example, the earliest monograph of traditional Chinese medicine "Shennong Materia Medica Classic" said that Prunella vulgaris has the power of "dispersing tumors and swelling, and breaking the accumulation of diseases", which has a good relief effect on some common unknown nodules, sores and fistulas or lumps caused by meridian stasis.
It is also clearly pointed out in "Herbal Medicine in Southern Yunnan" that Prunella vulgaris has a good effect of "dispelling stagnation of heat in the liver and promoting stagnation of qi in the liver", and it also has a good effect in clearing away liver heat and nourishing liver.
In modern times, Prunella vulgaris has three main uses. First, it has the efficacy of clearing liver heat and improving eyesight; Second, it has the value of calming liver yang, lowering blood pressure and relieving spasm; Third, it has the wonderful function of promoting qi stagnation, resolving phlegm and fire and eliminating carbuncle and scrofula.
1, the application of Prunella vulgaris in clearing away liver heat and improving eyesight
Prunella vulgaris has bitter and cold effects, and it mainly enters the two meridians of liver and gallbladder, which has a good effect of clearing away the excess heat and stagnation of fire in liver and gallbladder, while the heat and evil in liver and gallbladder are vigorous, and the time from inflammation to leader is most likely to cause various eye diseases.
For example, the common phenomena such as redness of eyes, eye pain, and redness of eyelids are mostly caused by the anger rushing to the leader.
In many folk places, people have the habit of harvesting spica Prunellae to make tea, which plays a very good role in clearing away liver fire, nourishing liver and improving eyesight.
It is also clearly stated in some ancient books on ophthalmology that Prunella vulgaris has the effect of "clearing away liver heat and stopping eye pain", and it is often used in combination with Cyperus rotundus and Sophora japonica, which has a good effect of clearing away heat evil in the liver and relieving eye pain.
2. Application of Prunella vulgaris in calming liver yang, lowering blood pressure and relieving spasm.
When the heat in the liver is strong for a long time, the hyperactivity of liver yang will disturb the upper focus. For example, in traditional Chinese medicine, it is believed that many common symptoms of high blood pressure, or dizziness and convulsions of the leader, are mostly caused by hyperactivity of liver yang disturbing the leader.
Prunella vulgaris not only has the effect of clearing away bitter cold and expelling liver fire, but also has the effect of dispersing pungent herbs and dispersing liver wind, which can obviously relieve symptoms such as high blood pressure due to hyperactivity of liver yang, dizziness of head, spasm and convulsion due to internal movement of liver wind.
In traditional Chinese medicine, Prunella vulgaris is often used in combination with concha Haliotidis, mother-of-pearl, Radix Rehmanniae, Semen Cassiae, Bombyx Batryticatus and other medicinal materials to alleviate the above situation, which has a certain good effect in lowering blood pressure and relieving spasm.
3. The application of Prunella vulgaris in stagnation of qi, eliminating phlegm and fire and eliminating gall and scrofula.
In modern times, the disease of carbuncle and scrofula mentioned by the ancients generally refers to some common diseases such as nameless nodules and masses in the body. Chinese medicine believes that these nameless nodules and masses are mostly caused by qi stagnation and blood stasis in the body, phlegm-fire accumulation and meridian stasis.
However, Prunella vulgaris has certain medicinal value in helping people to clear liver heat, promote liver qi and relieve liver depression. Taking Prunella vulgaris as medicine and combining with other drugs with syndromes often has a good effect of reducing swelling and resolving stagnation.
For example, some diseases caused by liver depression and qi stagnation, phlegm and blood stasis, etc., are commonly used by Chinese medicine in combination with Chinese angelica, Cyperus rotundus, Fritillaria thunbergii, white mustard seed, Scrophularia root, Shā rotto Katakuri, zedoary, etc., which has obvious effects of eliminating tumors and dispersing scrofula.
