Problems solved by technology

[0010] Existing palmatine preparations include injections, tablets, suppositories, etc. Although they are effective in treating gynecological and oral infections, the injections have harsh production process conditions, inconvenient use, low local drug concentration in the lesion, long treatment period, poor patient compliance, and many side effects. Disadvantages: Oral tablets have disadvantages such as large dose, gastrointestinal irritation, easy to cause intestinal flora imbalance, slow onset of action, low bioavailability, long treatment period, and low local drug concentration in lesions; although suppositories directly act on the disease-causing site, However, it is inconvenient to use, easy to be polluted, and a large amount of matrix affects the degree of drug action and release. When the ambient temperature is too high, it can absorb moisture and stick, and it is often easy to lose water when it is dry and becomes brittle, broken, deformed, discolored, sticky, melting, affect the use
