Podophyllum Resin is a topical cytotoxic medication used in the management of specific external skin growths and lesions.
Podophyllum resin is a plant-derived preparation obtained from the rhizomes of Podophyllum peltatum (commonly called American mandrake). It belongs to the class of botanical anti-viral agents and is mainly used for its ability to stop the growth of certain abnormal skin cells. In Hong Kong it is available only in medicines that are approved by the Department of Health. One well-known product that contains this resin is Podowart.
The primary marketed product that includes Podophyllum resin in Hong Kong is Podowart. It is sold as a topical solution that can be applied directly to the skin. The preparation is offered in a single strength, and the resin is the only active ingredient; there are no additional drugs mixed in the formulation. As a prescription-only medicine, Podowart must be dispensed by a licensed pharmacy under the supervision of a qualified practitioner. Generic versions are not currently listed in the Hong Kong Pharmaceutical Directory, so most patients will encounter the brand name.
Podophyllum resin is employed to manage a small group of skin conditions where abnormal cell growth is a concern.
In each case the resin works by halting the replication of the infected or abnormal cells, allowing the body’s normal healing processes to clear the area. The medication is intended for short-term, localized treatment rather than long-term systemic therapy.
When applied to the skin, the resin interferes with the way damaged cells divide. It temporarily stops the cells from multiplying, which limits the spread of the wart or lesion. Because the effect is confined to the area of application, the rest of the body is largely unaffected. Most users notice a slowing of growth within a few days, and the visible lesion often begins to shrink as normal skin replaces it.
These reactions are generally short-lived and do not require medical intervention unless they persist.
If any of these occur, seek immediate assistance at an Accident & Emergency department or call the Hong Kong Emergency Services number 999.

Store Podowart at room temperature, away from direct sunlight and moisture. Keep the bottle tightly closed to maintain potency. Treatment courses are usually brief, lasting only a few weeks, after which the medication is stopped. Always follow the specific instructions that accompany the product, as formulation details can vary between batches. Remember that the safety and effectiveness of each medication depend on correct use, so the label’s directions are essential.

Topical: Applied directly to the surface of the skin rather than taken by mouth or injection.
Wart: A small, rough growth on the skin caused by a viral infection.
