Those who are weak can take the water decoction of Prunella vulgaris and apply the ointment to the affected area. It is best to take Shiquan Dabu Decoction, Rhizoma Cyperi, Bulbus Fritillariae Cirrhosae and Radix Polygalae.
2, the role of Prunella vulgaris
1, hypotensive effect The water extract, ethanol water extract and 30% ethanol extract of Prunella vulgaris all have hypotensive effects on anesthetized animals. Injecting decoction (100 mg/kg) into anesthetized dogs can produce significant and lasting antihypertensive effect, but it is easy to produce rapid tolerance. For example, use a leather bridge to feed the dog Prunella vulgaris. 2 g/kg twice a day can also lower blood pressure; For dogs with renal hypertension, the blood pressure decreased moderately after two weeks of continuous medication, and then returned to the original level after drug withdrawal.
The stem, leaf, spike and whole grass of Prunella vulgaris have antihypertensive effect, and the spike effect is weak. After vagotomy, the hypotensive effect of Prunella vulgaris was obviously weakened. Excitement was observed in in situ and isolated rabbit hearts and isolated toad hearts, and it was considered that hypotension was not caused by cardiac inhibition. In the perfusion of toad's lower limbs, decoction can dilate blood vessels. When the total maple-free salt content of Prunella vulgaris is equivalent to the decoction amount, there is no obvious antihypertensive effect. When the total salt-free content of Prunella vulgaris is more than 2 times that of the decoction, the degree of blood pressure reduction is only 1/4 ~ 1/6 of the decoction. Although the antihypertensive effect appeared late, it lasted for a long time, so it is considered that the antihypertensive effect of Prunella vulgaris has nothing to do with its inorganic salts.
In recent years, some people have repeatedly verified the above experiments, and found that the potassium content in the tincture of Prunella vulgaris stem and leaf (30% alcohol) is quite high, about 83 meq/ml, and the content in the ear is less; Oral administration has no obvious antihypertensive effect on normal anesthetized dogs; After removing the inorganic salts in the decoction, the hypotensive effect is very small, that is, the hypotensive effect of Prunella vulgaris on anesthetized animals cannot be ruled out, so it is necessary to study its hypotensive components and hypotensive principle.
2. Antibacterial effect According to the preliminary test in vitro, Prunella vulgaris decoction has inhibitory effect on Shigella, Typhoid Bacillus, Vibrio cholerae, Escherichia coli, Proteus, Pseudomonas aeruginosa, Staphylococcus and Streptococcus, and its antibacterial spectrum is also wide. Its aqueous solution (1: 4) also has a certain inhibitory effect on some common pathogenic dermatophytes in vitro. For experimental pulmonary tuberculosis in mice, Prunella vulgaris can alleviate lung lesions.
3. Other effects: Spica Prunellae Decoction (1: 50 ~ 1: 200) can cause rigidity contraction of isolated rabbit uterus. For isolated rabbit intestine, high concentration can enhance peristalsis. It has been reported that Prunella vulgaris decoction can inhibit the growth of S- 160 tumor and Ehrlich ascites carcinoma in mice, but the mortality rate is higher than that of the untreated group, so it is actually its toxic effect.
3. How to eat Prunella vulgaris
Prunellae Spica is Prunellae Spica or Prunellae Spica of Labiatae. The taste is bitter and cold, the fragrance dissipates, and it can rise or fall; Has that effect of clearing away live fire, relieving swelling and removing toxic substance, and can be used for treating headache, dizziness, tinnitus, eye pain, hepatitis and other diseases. It is most suitable for drinking in recent hot and humid weather.
But not everyone can eat Prunella vulgaris, and people with weak spleen and stomach, children, pregnant women and menstrual women are not suitable. Because long-term use of selfheal saponin is irritating to the stomach. In addition, it may also cause allergic reactions: measles, papules or erythema on the skin, itching all over the body, stomach discomfort, nausea, vomiting, dizziness, dizziness, abdominal pain, diarrhea, palpitations and so on. Therefore, before eating Prunella vulgaris, citizens should have a general understanding of their bodies and avoid eating it indiscriminately. Otherwise, it will not only fail to reduce the "fire", but also aggravate the condition. In addition, because of the cold nature of Prunella vulgaris, it is not advisable to eat more, just once a week.
