Efficacy and purpose

Licorice is a plant with significant medicinal value, which is commonly used in traditional Chinese and Western medicine. Western medicine has been using licorice as an expectorant, cough suppressant, and sweetener since ancient Greece. In the ancient Chinese pharmacology “Shennong Materia Medica Classic”, licorice is described as a medicine that strengthens muscles and bones, increases physical strength, and treats wounds, and is listed as the top grade. It is called the king of various medicines, and there are few prescriptions that are not used.

In traditional Chinese medicine, licorice is classified as the heart, lungs, spleen, and stomach meridians; It has the effects of tonifying the spleen and tonifying qi, clearing heat and detoxifying, dispelling phlegm and relieving cough, relieving pain slowly, and harmonizing various herbs. Used to treat spleen and stomach weakness, fatigue, palpitations, shortness of breath, coughing and phlegm accumulation, abdominal and limb cramps and pain, carbuncle, swelling, and sores, and to alleviate drug toxicity and intensity. The dosage is 1.5-9mg.

Research shows that licorice has the effects of inhibiting monoamine oxidase, inhibiting aldose reductase that causes diabetes, relieving spasm and analgesia, preventing and treating viral hepatitis, treating senile osteoporosis, resisting leishmaniasis, cancer, and AIDS virus.

Its efficacy is reflected in two aspects: whitening and sun protection

The whitening effect of licorice extract is mainly achieved by inhibiting the activity of tyrosinase and dopachrome tautometase (TRP-2), hindering the polymerization of 5,6-dihydroxyindole (DHl), thereby preventing the formation of melanin and achieving the effect of whitening the skin.

The components with sunscreen effect in licorice extract are generally flavonoids. Due to the conjugation of the molecular structure of licorice flavonoids, they exhibit strong absorption of both ultraviolet and visible light. Molecules that absorb high-energy ultraviolet light transition from the ground state to the activated state, and then return from the activated state to the ground state, releasing harmless low-energy rays. Compared to synthetic sunscreens, licorice extract used as a sunscreen does not require the addition of antioxidants in the formula, does not irritate the skin, and has strong stable absorption ability.
