Abstract

The invention discloses a cannabis sativa leaf extract as well as a preparation method and application thereof. The cannabis sativa leaf extract contains 0.30-0.93 g/g of cannabidiol and 0.05-0.08 mg/g of tetrahydrocannabinol. Wherein cannabidiol is a main medicinal component for inhibiting gingival bleeding and dental calculus; the content of tetrahydrocannabinol is far lower than the content standard of 0.3% (w/w), and the product is safe and free of addiction. The cannabis sativa leaf extract has the effects of inhibiting gingival bleeding and dental calculus, and particularly, after the cannabis sativa leaf extract and the ginkgo leaf extract form the oral care composition, the combination advantage is reflected, the dosage is reduced, and the curative effect is improved. The toothpaste prepared from the oral composition can better improve the healthy environment of teeth and gingiva, consolidate the gingiva structure and effectively treat gingival bleeding and dental calculus, is free of preservatives, is a pure natural, green, safe and effective toothpaste product, and has market popularization prospects.

Description

technical field [0001] The invention relates to a natural plant extract, in particular to a cannabis leaf extract and its preparation method and application. Background technique [0002] Dental calculus is a calcified and partially calcified substance attached to the surface of the teeth. It is an important pathogenic factor in the development of periodontal disease. The clinical manifestations are gingival recession, gingival bleeding, bad breath, and loose teeth. Gingival inflammation refers to acute and chronic inflammation that occurs in gingival tissue. The clinical manifestations are gingival bleeding, redness, swelling, and pain. It continues to develop and invade hard tissues, resulting in periodontitis, including inflammation of gingival tissue and a manifestation of systemic diseases in the gingiva. Bleeding gums are often the main subjective symptoms of gingivitis patients. They often occur when brushing teeth or biting hard objects, and occasionally there may be...
