pharmacological action

1, salivation effect: Dendrobium candidum has salivation effect, mainly in promoting gland secretion and organ movement.

2. Hypoglycemic effect: Dendrobium candidum can reduce the blood sugar level of streptozotocin-induced diabetes.

3. Enhance immunity: Dendrobium candidum granules (TPSH) can promote the phagocytosis of macrophages of tumor-bearing animals, enhance the proliferation and differentiation of T lymphocytes and the activity of NK cells, and significantly increase the serum hemolysin value of tumor-bearing animals, suggesting that TPSH can simultaneously improve nonspecific immunity, specific cellular immunity and humoral immunity.

Extended data

It is distributed in southwest Anhui (Dabie Mountain), east Zhejiang (Yinxian, Tiantai and Xianju), west Fujian (Ninghua), north Guangxi (Tiane), Sichuan and southeast Yunnan (Shiping, Wenshan, Malipo and Xichou).

The cultivation time of Dendrobium candidum is generally in spring and autumn every year, and spring is better than autumn. In Zhejiang, the best cultivation time of Dendrobium candidum is from mid-April to late June every year, during which the temperature is 65438 02 ~ 25℃, the air humidity is high, and the survival rate of transplanted test-tube seedlings is high and the growth time is long. Followed by mid-September to 10. In the meantime, it is especially necessary to do a good job in cold and antifreeze.
