Bamboo Yellow

Bamboo yellow is a blocky substance formed by the sap accumulated in the bamboo nodes of the grass family green-skinned bamboo after being bitten by parasitic bamboo wasps. It condenses after drying. It is harvested in winter, and the bamboo stalks are cut, the bamboo yellow is cut and dried. This product is rarely produced naturally. Most of them are produced by burning bamboo forests, so that the bamboo juice overflows and solidifies in the internodes after being exposed to intense heat, and then cut and dried. It is mainly produced in Yunnan, Guangdong, Guangxi and other places. It has the effects of dispelling wind and dampness, promoting blood circulation and relaxing the meridians, and relieving cough. It is used for rheumatic pain, numbness of the limbs, whooping cough in children, and excessive leucorrhea. It is said to be able to treat stomach problems.

The efficacy and function of bamboo yellow

1. Treat colds and epidemic diseases, fever and lethargy, rough breathing, cough due to wind-heat and phlegm congestion, convulsions, heatstroke, and also treat leucorrhea in virgins: 1 liang of Tianzhuhuang, 1 qian of realgar (water-ground), 0.5 liang of cinnabar and musk (ground separately), 4 liang of Tiannanxing (brewed in cow bile in the twelfth lunar month, dried in the shade for 100 days. If not available, just peel and fry the raw ones until dry). Grind the above into fine powder, boil licorice water and make pills as big as soap seeds, dissolve in warm water and take. For a 100-day-old child, divide each pill into three or four doses, one or two pills for five-year-olds, and three or five pills for adults. In the dog days of summer, use a little salt, chew one or two pills, and drink fresh water; in the middle of the twelfth lunar month, boil licorice in snow water and make the medicine.

2. Treat acute convulsions in children: 1 qian of Indigo and Light Powder, 5 qian of Morning Glory Powder, 2 qian of Rhizoma Cibotii. Grind the above into powder, make pills with white flour paste, as big as red beans, take 20 pills each, and drink with mint soup. (Lijing Pills in "Xiaoer Yaozheng Zhijue")

3. Treating nosebleeds: Tianzhuhuang, Chuanxiong, 1 fen each, Fangji half a liang. Grind the above three ingredients into powder. Take 1 qian spoonful each time, and drink with fresh water. For lung damage and vomiting blood, use 2 qian spoonfuls of medicine and 1 qian spoonful of raw flour, mix with water and drink after meals. (Tianzhuhuang powder in Shengji Zonglu)

4. Rheumatism, numbness of limbs: soak 60g of bamboo shoots in 250ml of white wine for 24 hours and take it once a night, about 50ml, or rub it externally with medicated wine.

5. Whooping cough in children: 6-9g of bamboo shoots, decocted in water and taken orally.

Nutritional value of bamboo shoots

Two kinds of polysaccharides were isolated from the mycelium fermentation broth: SB-1 and SB-2; the former is composed of D-glucose, D-galactose and L-arabinose in a molar ratio of 0.37:1:0.07, and the latter is composed of D-glucose, D-galactose, D-mannose and L-arabinose in a molar ratio of 0.25:1:0.47:0.12. Protease, amylase, D-mannitol, aspartic acid, threonine, serine, glutamic acid, glycine, alanine, cystine, valine, methionine, isoleucine, phenylalanine, lysine, γ-aminobutyric acid, tyrosine and trace cysteine ​​were obtained from the water-soluble components. Hypocrellin A, B, C, mannitol, stearic acid were obtained from the fruiting body. Shiraiachrome A, B, C were also obtained.

The medicinal value of bamboo

1. The decoction of the fungus Bamboo Huang can weaken the contractility of the isolated frog heart and slow down the heart rate. The effect is more intense at a concentration of 1×10\-2g.

It has a direct dilating effect on isolated rabbit ear vessels, which is manifested as an increase in perfusion volume, especially when the blood vessels are in a state of contracture. 3.0g/kg of the extract of the fungus bamboo yellow decoction was injected subcutaneously into the back of mice, which had a very significant inhibitory effect on the increase in skin capillary permeability caused by histamine. Intravenous injection of 0.5g/kg of the extract can reduce the blood pressure of anesthetized rabbits. Its mechanism may be related to affecting cardiac output and dilating arterioles, reducing peripheral resistance.

2. Effects on cardiovascular system and plasma recalcification time A concentration of 2×10\-1g can significantly prolong plasma recalcification time. In the blood coagulation experiment, the drug can prolong the coagulation time, which may be related to the prolongation of the recalcification time.

3. Analgesic and anti-inflammatory effects: Subcutaneous injection of 2-3.1g/kg of the decoction of the fungus bamboo yellow has a good analgesic effect on the acetic acid irritation pain in mice. The crystallized substance III (bamboo fungus A) extracted from bamboo yellow, when administered orally at 100mg/kg, can significantly increase the pain threshold of the hot plate test in mice. Its effect is better than indomethacin (indomethacin) and similar to that of d-butanol (10mg/kg); it can significantly reduce the number of writhing reactions caused by acetic acid, and can also significantly reduce the degree of plantar swelling caused by egg white.

4. Other effects: Preliminary pharmacological tests have shown that fungal bamboo polysaccharides SB1 and SB2 have certain therapeutic effects on hepatitis.

5. When 15g/kg of the decoction of the toxic fungus Rhizoma Corydalis was gavaged into mice, the mice were able to move freely and eat normally within 72 hours without any adverse reactions. The LD50 of intravenous injection into male mice was 6.471g/kg.
