The difference between yellow grass and Dendrobium candidum

Dendrobium henryi is the stem of Dendrobium henryi, an orchid plant. Its flowering period is from March to September. Today, I will introduce you to the difference between yellow grass and Dendrobium officinale.

1. The difference between yellow grass and Dendrobium officinale

1. Different taste

Dendrobium officinale has more residue and less colloid when eaten. It doesn't taste as waxy as Dendrobium officinale. This is a relatively direct judgment method.

2. Different shapes

The diameter of the maple bucket section made by Dendrobium officinale is generally less than 5 mm, and its workmanship is also relatively fine, but Dendrobium officinale can't do this because of its large size.

3. Different yields

Dendrobium huangcao growth environment requirements are not very high, usually harvest once a year, and yield per mu is relatively high. Dendrobium officinale has high requirements for growth environment, and its yield cannot meet the market demand, so it is rarely used as medicinal materials.

II. Pharmacological effects of Dendrobium officinale

1. Shengjin effect: Dendrobium officinale has the effect of producing saliva, mainly manifested in promoting gland secretion and organ movement.

2. Hypoglycemic effect: Dendrobium officinale can reduce streptozotocin induced diabetes blood glucose value.

3. Enhancement of immunity: Dendrobium officinale granules (TPSH) can promote phagocytic function of macrophages, enhance proliferation and differentiation of T lymphocytes and NK cell activity of tumor-bearing animals, and can obviously increase serum hemolysin value of tumor-bearing animals, suggesting that TPSH can improve non-specific immune function, specific cellular immunity and humoral immune function to some extent.

Dendrobium officinale is born on the semi-damp rocks in the mountains at an altitude of 1600 meters. It is mainly distributed in Anhui, Zhejiang, Fujian and other places in China.
