Treatment of actinic keratoses with a novel betulin‐based oleogel. A prospective, randomized, comparative pilot study

Background: Actinic keratoses (AK) are squamous cell carcinomas in situ and require treatment. Betulin‐based oleogel prepared from a standardized triter‐pene dry extract from birch bark represents a new topical agent with anti‐inflammatory and anti‐tumor potential.

[Treatment of actinic keratoses with birch bark extract: a pilot study].

Background: Birch bark contains a variety of apoptosis‐inducing and anti‐inflammatory substances such as betulinic acid, betulin, oleanolic acid and lupeol. Therefore, birch bark extract may be effective in the treatment of actinic keratoses. To address this issue, a pilot study using a standardized birch bark ointment was performed.
