Plants in the Asteraceae family have a long history of traditional use for various skin conditions, including dermatitis. Common genera from this family, such as Calendula (marigold), Arnica, and Chamomilla (chamomile), are frequently cited in folk medicine and traditional herbal texts for their purported anti-inflammatory and soothing effects on the skin. Extracts, teas, and topical preparations from Asteraceae plants have been applied to inflamed or irritated skin to reduce redness, itching, and swelling.

The rationale for their use is largely based on observed effects in traditional practice and anecdotal reports. For example, topical Calendula officinalis ointments are a well-known remedy in European herbalism for minor wounds and skin inflammation. Likewise, chamomile preparations have been used in baths and compresses for eczema and dermatitis. While some small-scale studies and in vitro research suggest anti-inflammatory and wound-healing properties in certain Asteraceae extracts, robust, high-quality clinical trials are limited. Most data supporting their use for dermatitis is derived from historical accounts, ethnobotanical surveys, and traditional pharmacopeias, rather than modern scientific validation.

In summary, the use of unspecified Asteraceae plants to support or treat dermatitis is primarily justified by traditional use rather than strong scientific evidence.
