(1) The role of turmeric
- Choleretic effect.
Turmeric decoction and infusion can increase bile secretion in dogs, restore bile components to normal, and increase gallbladder contraction. Its effect is weak and long-lasting, which can last for 1-2 hours. Curcumin or its sodium salt has anti-cholesterol effects. When injected intravenously in dogs, it can reduce the content of solid components and increase the secretion of bile, but from the total absolute value, the secretion of bile salts, bilirubin, and cholesterol all increase. The fatty acid composition remains constant. The volatile oil proposed in another plant of the same genus increases bile secretion, and the pigment causes gallbladder contraction. Curcumen is a cholesterol solvent and can be used to treat biliary stones. 50% turmeric decoction can promote appetite.
- Antibacterial, anti-inflammatory and analgesic.
Curcumin and volatile oil have good antibacterial effects on Staphylococcus aureus. Turmeric water infusion can inhibit various skin fungi to varying degrees in the test tube. The decoction can prolong the survival time of mice inoculated with the virus, but it is not effective for adding chemical (carbon tetrachloride) liver damage to the tomb of viral hepatitis. In addition, turmeric preparations can kill flies. Its volatile oil and curcumin have significant anti-inflammatory effects on acute and subacute foot swelling inflammation in rats and mice. Its decoction has analgesic effect.

Turmeric alcohol extract, turmeric volatile oil and curcumin all have significant effects on lowering serum cholesterol, triglycerides, and β-lipoprotein.
Turmeric alcohol extract has the effect of lowering blood pressure on anesthetized dogs. Curcumin has the effect of increasing myocardial nutritional blood flow.

At 0.4mg/ml, it can inhibit the growth of Chinese hamster ovary cells, has a cytotoxic effect on lymphocytes and Dalton’s lymphocytes, and can reduce the growth of animal tumors. Its active ingredient is mainly curcumin.
- Light effect.
Curcumin has a weak bactericidal ability under normal circumstances, but when exposed to light, the microgram amount of curcumin shows a strong phototoxic reaction. Gram-negative bacteria are more resistant to curcumin phototoxicity than Gram-positive bacteria. The phototoxicity of curcumin can only be produced under aerobic conditions. Therefore, curcumin may be used as a photosensitizer for phototherapy of psoriasis, cancer, bacteria and viral diseases. Curcumin can also stabilize the photodegradable drugs. For example, the photostabilization effect of nifedipine is particularly strong, which can extend its half-life by 6 times and enhance its curative effect.
