What ointment is effective for treating warts on fingers?

"Houzi" likely refers to warts. Applying tretinoin cream, salicylic acid ointment, or recombinant human interferon α2b gel on warts located on the fingers can be effective. The details are as follows:

1. Tretinoin Cream

If a patient frequently bites their nails or shares personal items with others, human papillomavirus (HPV) may enter the body through damaged skin on the fingers, leading to benign skin growths and causing this condition. Warts typically appear as localized grayish-brown raised lesions and may cause mild itching. Tretinoin cream helps regulate growth factors, remove dead surface skin, accelerate tissue renewal, and promote the shedding of warts.

2. Salicylic Acid Ointment

Salicylic acid ointment softens keratin and causes cell adhesion to break down, thereby relieving itching and alleviating itchiness at the affected site.

3. Recombinant Human Interferon α2b Gel

Recombinant human interferon α2b gel has antiviral properties. After application, its active ingredients bind to receptors and inhibit viral replication. It also enhances lymphocyte activity and boosts the body's immune response.

In addition, patients may also use medications such as imiquimod cream, podophyllotoxin tincture, or tazarotene gel. It is recommended that patients use these medications under the guidance of a physician and monitor changes at the affected site after treatment.
