Whether or not a patient with nail infection can be treated with Yunnan Baiyao powder as an anti-inflammatory treatment depends on the severity of the local infection. A. If the local inflammation of nail infection is mild, with only mild redness, swelling and pain. In this case, the local inflammation of the nail can be better controlled by applying topical Yunnan Baiyao powder, avoiding repeated stimulation of the local granulation tissue, and wearing loose shoes. If the local nail infection is heavy, with obvious redness, pain, limited nail activity or abscess formation. In this case, the topical application of Yunnan Baiyao powder is not a good anti-inflammatory effect. It is necessary to perform local abscess incision and drainage as soon as possible, remove the inflammatory necrotic tissue from the trauma, and perform nail extraction and nail bed shaping if necessary to avoid recurrence of nail infection.
