Abstract

The invention discloses centella asiatica floral water and a preparation method and application thereof. Fresh centella asiatica is picked, washed, subjected to impurity removal, cut and placed in a distiller, hot deionized water is added for soaking, then the temperature is increased and distillation is conducted, circulating cooling liquid is introduced, condenser distillate is collected, distillation stops when the volume of the collected distillate is 0.8-1.2 times of the mass of fed centella asiatica, the distillate is filtered and sterilized through a microporous filter membrane with the aperture of 0.22 micrometer, and the centella asiatica floral water is obtained. The obtained floral waster is clear and transparent, has the special fragrance of centella asiatica floral water, is stable in quality, and can be stored for one year in a sealed mode at low temperature. Inedible chemical components are not added in the extraction process, and it is guaranteed that the floral water is natural and free of toxin, has a repair function on scarred and wounded skin, has anti-inflammation and antibacterial functions on acne skin, can accelerate skin regeneration, relieves sensitive skin, reduces irritation and meanwhile provides sufficient moisture for skin.
