Antibacterial effect: clove can inhibit the growth of staphylococcus and mycobacterium tuberculosis. Perfume decoction and powder have strong antibacterial effect on hemolytic streptococcus, and its antibacterial effect is not affected by heating. Experiments show that the alcohol extract of clove has inhibitory effect on diphtheria, anthrax, paratyphoid fever, dysentery, Staphylococcus aureus, Staphylococcus albicans and Vibrio cholerae.
Effect on digestive system: Clove is an aromatic stomach tonic, which can relieve flatulence, enhance digestion and reduce nausea and vomiting. Studies have shown that clove extract can stimulate the secretion of gastric acid and pepsin, which is different from acetylcholine. The former stimulates gastric acid secretion with strong digestibility, while the latter stimulates gastric acid secretion with low acidity.
Insect repellent effect: In the test tube, clove ethanol extract, water decoction and clove oil can paralyze or kill ascaris suum. Clove oil is better than water. 0.5 ~ 1.0g/kg clove oil can make the dogs infected with ascaris excrete ascaris without side effects. However, when the dosage is increased to 5g/kg, it will cause vomiting and reduce the efficacy of insect repellent.
Other effects: intravenous injection of eugenol in rabbits can produce anesthesia, blood pressure drop, respiratory inhibition and obvious anticonvulsant effect. Eugenol can strongly inhibit prostaglandin biosynthesis in vitro. A small amount of clove oil dripped into the cavity of dental caries can not only disinfect, but also destroy its nerves, thus relieving toothache. Cloves can also cause uterine contractions.
Lilac: Oleaceae, deciduous shrub or small tree. Because the flower tube is slender as nails and fragrant, it is named Harbin Flower, which is a famous garden flower. Clove inflorescence is huge and luxuriant, with elegant and fragrant color, strong habit and simple cultivation, which is widely cultivated and applied in gardens.
Clove is used as medicine together with bud and its fruit. Buds are called cloves, and fruits are called female cloves or female cloves. When the buds begin to turn white, gradually turn green and finally turn bright red, they can be harvested. Remove the pedicels from the collected flower buds and dry them in the sun. Clove oil and eugenol have good medicinal value.
