Embodiment 1

[0018] ⑴The components are: dry alum 49%, clam shell powder 27%, camphor 24%.

[0019] (2) The process preparation steps are as follows:

[0020] 1) Raw material preparation: remove impurities from the raw material components, wash, dry, pulverize, pass through a 60-mesh sieve, and take the sieved material to obtain a mixed powder;

[0021] 2) Extraction: Using supercritical extraction equipment, put the mixed powder into the extraction kettle of the supercritical CO2 extraction equipment, add ethanol with an entrainer content of 60% to immerse the mixed powder, use supercritical CO2 as the extraction solvent, and extract at a temperature of 30 ℃, the extraction pressure is 30Mpa, the extraction time is 4h, and then the temperature is raised and the pressure is lowered for separation, and the product in the separation tank is collected to obtain the extraction powder;

Abstract

The invention discloses CO2 supercritical extraction based damp and heat clearing powder and a preparation method thereof. The CO2 supercritical extraction based damp and heat clearing powder comprises dried alum, clam shell powder and camphor and is prepared by CO2 supercritical extraction. Through CO2 supercritical extraction, active components can be completely extracted; the steps are simple,and the cost is saved. Compared with conventional methods, the preparation method has the advantages of high extraction rate, low operating temperature, no damage to the traditional Chinese medicinalactive components, no organic solvent residue and simple process. The CO2 supercritical extraction based damp and heat clearing powder has the functions of drying dampness, stopping diarrhea and bleeding, removing toxic materials and killing parasites, has quick action and strong penetration ability, and has the effects of quickly relieving stuffiness, removing stagnation and turbidity, killing the parasites, and relieving itching, swelling and pain.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a CO2 supercritical extraction powder for dispelling dampness and clearing heat and a preparation method thereof. Background technique [0002] Underarm odor is commonly known as body odor. The main symptom is that the armpit and other folds emit an unpleasant smell, which affects the social life of the patient. In severe cases, it can lead to psychological disorders of the patient. Underarm odor patients will sweat abnormally and emit an unpleasant smell when the ambient temperature is high or the mood is tense. Excessive sweating and body odor will stain clothes yellow and leave a long-lasting smell, causing cleaning troubles. This symptom is most obvious in adolescence, and it is easy to aggravate in hot summer. Body odor is also hereditary and related to gender and racial differences. In Westerners, body odor is also known as: "body odor", which means...
