Efficacy and function of Dendrobium nobile

The Compendium of Materia Medica says it has the effect of "strengthening yin and nourishing essence, thickening intestines and stomach, replenishing lack of endospora, lightening body and prolonging years". In history, doctors said that Dendrobium nobile was "dry but not haggard, chewed and without residue stains, strong taste and no fat ointment, nourishing stomach beneficial fluid, but not cool hindering the spleen."

Instead of tea, Shengjin moistens the throat, the voice does not decline; take it to extract, antibacterial and anti-cancer, delay aging. Therefore, the efficacy is strange, the market is scarce, known as "golden grass", "soft gold" said! Its main effects are as follows:

1. Anti-aging, improve immunity

Dendrobium nobile can significantly increase the level of superoxide dismutase (SOD), reduce lipid peroxidation (LPO), regulate the level of monoamine neurotransmitters in the brain, inhibit monoamine oxidase (MAO), and delay aging.

Dendrobium polysaccharides which have attracted much attention in recent years also have significant immune enhancement activity and anti-aging, anti-radiation and other effects. Proprietary Chinese medicines and health products that have been developed are favored by people, such as Jinfeng Doujing, Dendrobium Powder, Qingyanning, Yichang decoction, Dendrobium dew, Dendrobium essence, Yangyin Oral liquid and Dendrobium tablets.

2. Promoting blood circulation and removing blood stasis to improve cardio-cerebrovascular function.

Dendrobium nobile contains esters, which has the functions of promoting blood circulation and removing blood stasis, dilating blood vessels and anti-platelet coagulation, treating thrombus occlusive pulse angiitis, cerebral thrombosis, arteriosclerotic occlusion and so on. Mailuoning injection, which is extracted and processed from Dendrobium and honeysuckle, has the functions of clearing heat and nourishing yin, promoting blood circulation and removing blood stasis.

3. Anti-tumor

Phenanthrene and bibenzyl extracted from Dendrobium nobile have anti-lung cancer, ovarian adenocarcinoma and promyelocytic leukemia. It can promote the growth of T cells and the production of inhibitory factors by lymphocytes, and play a role in enhancing immunity.

The ethyl acetate extract of Dendrobium nobile has significant cytotoxic effects on human lung cancer cells, human ovarian adenocarcinoma cells and human promyelocytic leukemia.

4. Treatment of digestive system diseases

Dendrobium nobile has an exciting effect on the intestines and can increase the amplitude of contraction. Pharmacological tests show that oral Dendrobium decoction can promote gastric juice secretion and help digestion.

The effect of Dendrobium alkaloid is similar to that of non-Xetine, but its effect is weak. Dendrobium extract can stimulate the contraction of small intestinal smooth muscle and promote gastrointestinal peristalsis. It can get unique and satisfactory effect on chronic atrophic gastritis.

5. Treatment of ophthalmic diseases

Dendrobium nobile has obvious therapeutic effect on ophthalmic diseases, not only has an inhibitory effect on galactose cataract, but also has a certain therapeutic effect, and the percentage of lens is 36.8%.

In the treatment of cataract, it can not only inhibit the abnormal changes of enzyme activity caused by galactose, but also prevent or correct the imbalance of lens total lipid to total cholesterol caused by galactose cataract. "Dendrobium Night Light Pill" is composed of 25 Chinese herbs such as Dendrobium and Ginseng, which has a good effect on the treatment of cataract, glaucoma, optic neuritis and so on.

What is the difference between Dendrobium and Dendrobium?

External view

The difference between the two is mainly distinguished by appearance. The color of Dendrobium flowers is pink and white, and the front segment gradually tends to purplish red, each flower has six petals.

On the other hand, the flowers of Dendrobium candidum are yellowish, with as few as seven or eight flowers on each scape, more than twenty or more, and each flower has six petals, showing the shape of flowers scattered on all sides.

Taste

The main difference between Dendrobium nobile and Dendrobium candidum is the content of Dendrobium alkaloids and polysaccharides. The alkali content of Dendrobium nobile and Dendrobium candidum is less than that of Dendrobium nobile, which is also the reason why Dendrobium nobile is bitter and Dendrobium candidum is not bitter.

The more bitter Dendrobium nobile is, the higher the content of Dendrobium alkaloid is, the higher its medicinal value is. And Dendrobium candidum has more polysaccharide content, so Dendrobium candidum is not bitter, gelatinous and sticky. That is why there is a saying that gold hairpin is selected for medicinal use and tin for health care.

Component

Scientific studies have shown that the relative integral areas of even mass numbers of chromatographic peaks in Dendrobium candidum and Dendrobium nobile are 2.34% and 41.87%, respectively. Conclusion: there is a great difference in the quantity and content of alkaloids between Dendrobium candidum and Dendrobium nobile, but in terms of the same chemical components, the quality of Dendrobium candidum is better than that of Dendrobium nobile.
