How much do you know about the efficacy, function and taboo of vervain (pure dew, tea)?

When it comes to vervain, many people may only know that it has ornamental value, but few people know its medicinal value. In fact, verbena is a perennial herb, which is generally wild, mainly grows in the edge of the forest or wild grassland, originated in Europe, and is widely distributed and planted in East China, South China and Southwest China. Although vervain is a grass, it is also a kind of Chinese herbal medicine with high medicinal value. What are the effects, functions and taboos of vervain and vervain pure dew and verbena tea made from verbena?

I. the efficacy, function and taboo of vervain

Verbena contains verbena glycoside, cardiotonic glycoside, tannin and volatile oil. Stachyose in the rhizome. Leaves contain adenosine and β-carotene. Its effects and functions are mainly as follows:

1. Anti-inflammatory and analgesic effect

Both water and alcohol extracts have anti-inflammatory effects on inflammation caused by instillation of mustard oil into rabbit conjunctival sac, and the anti-inflammatory effect of the latter is better than that of the former. The water-soluble part of the latter is better than the water-insoluble part. The water extract had analgesic effect on the pain caused by electrical stimulation of rabbit tooth pulp, which began at 1 h and disappeared at 3 h, while the analgesic effect of alcohol extract disappeared completely after 6 h, and the water-soluble part had more analgesic effect, while the water-insoluble part had no analgesic effect.

2. Detoxification and antitussive effect

Verbena decoction has the effect of detoxification, can reduce swelling and diuresis, and has a certain antitussive and antitussive effect on cough caused by various causes. In ancient China, it was often used to treat cold and heat caused by malaria. The effective antitussive components are β-sitosterol and verbena glycoside.

3. Effect on uterus

Verbena at the concentration of 1.6 × 10-2g/ml has a certain excitatory effect on rat uterine muscle strips and non-pregnant human uterine muscle strips. In the rat uterine muscle strips, the specimens in estrus were the most sensitive to vervain, and the addition of vervain often caused both tension and contraction amplitude to increase at the same time, while the specimens in other stages often only increased the contraction amplitude. The response of human uterine muscle strips to vervain is weak, generally only catatonic changes take place. In the experiment of uterine muscle strips in rats, verbena and PGE2 could enhance each other, but only had an additive effect with PGF2a. When the concentration of verbena was enough to stimulate uterine smooth muscle, it had no significant effect on jejunal smooth muscle, nor could it enhance the effect of PGE2 on jejunal smooth muscle.

Vervain has many effects and functions, such as 10 jin of verbena and sage, boiling with water to remove dregs, making balls, and taking two to three pills a day to treat abdominal distension and abdominal pain. Vervain can also treat bulging, irritation and thirst. In addition, vervain can also excite the sympathetic nerve and promote milk secretion.

Using verbenone rosemary lotion with steamed face or hot compress can help the skin bring dirt to the surface, dredge clogged pores, deeply clean, and make the skin firm and increase the fineness of the skin.

After listening to some excellent teachers' opinions on the energy of the human body, I firmly believe that the power of nature has a healing effect. When people feel tired, pressure, low energy, you can warm the pure dew and slowly pour it into the hair along the forehead, which can be adjusted to replenish the body energy. Let the body and mind calm and relax.

3. Detoxification by oral administration

One of the best pure lotions for nourishing the liver and protecting the liver, I think it has a more obvious effect on clearing the respiratory system and mucous membrane. The diluted aroma has a hint of grass.

Two major misunderstandings of verbena tea:

1. Brew verbena tea in an insulated cup

Ceramic pots and cups should be used to make tea, not insulation cups. Because the tea is soaked in an insulation cup, the tea must be kept at high temperature for a long time, so that the aroma is reduced; too much tannic acid and theophylline are leached, and there is also a bitter taste, thus losing some nutrients.

2. Brew tea in boiling water

Making tea with boiling water will destroy a lot of nutrients. Therefore, the water temperature of making tea should be controlled at 70 ℃-80 ℃.
