1. What is its main role?
Hawthorn extract can promote the secretion of digestive enzymes in the stomach to promote digestion. Contains lipase can promote the decomposition of fat digestion; contains a variety of organic acids, vitamin C can improve pepsin activity, promote protein digestion. Hawthorn extract on the regulation of gastrointestinal function, hyperactivity of rabbit duodenal smooth muscle was inhibited, while the relaxation of gastric smooth muscle in rats with mild increase in contraction
2. What is the effect on heart disease?
Hawthorn has enhanced myocardial contractility. Increase cardiac output, slow down the rhythm of the role. Hawthorn extract in vivo, isolated toad cardiac contractility increased, and the duration of a long time. The triterpenic component, maslinic acid, has a recovery effect on the cardioplegia of the fatigue of the toad heart, but its duration is short. In this case,
3. Is cancer effective?
Hawthorn mice Ehrlich ascites carcinoma cells significantly inhibited. The decoction of Hawthorn seed decoction on human cervical cancer JTC-26 in vitro inhibition rate of 50% to 70%. Hawthorn tablets decoction can extend the life of transplanted tumor animals. The results showed that the survival rate of cancer cells decreased significantly when the dose of hawthorn extract was 4 ~ 8μg / ml, and the colony formation rate of cancer cells was significantly inhibited under the dose of 8 ~ 10μg / ml. Normal human cells no significant effect.
