Can Fuyanjie be used directly without diluting with water?
For women using Fuyanjie to clean the external genitalia, direct application without dilution is generally not recommended.
Fuyanjie is a commonly used gynecological wash in clinical practice, made from traditional Chinese herbs such as Sophora flavescens (Ku Shen) and Cnidium monnieri (She Chuangzi), with matrine as its main active ingredient. Fuyanjie can rapidly kill pathogenic bacteria such as Staphylococcus aureus, providing both cleansing and antibacterial effects. However, the undiluted solution is relatively irritating and may cause discomfort such as itching or stinging, especially in women who already have genital ulcers. Therefore, it is usually recommended that women dilute Fuyanjie with water before use.
Fuyanjie may be used as an adjunct treatment during episodes of vaginitis, but prolonged use could disrupt the normal vaginal flora, potentially worsening inflammation. Users should monitor skin reactions during application. If obvious signs of allergy occur, usage should be stopped immediately, and medical attention should be sought promptly.
