Southernwood (Artemisia abrotanum) has a long history of traditional use in European herbal medicine, particularly for its aromatic and antiseptic properties. In folk medicine, it was often applied externally in the form of poultices or washes to help cleanse minor wounds, scratches, and abrasions, with the belief that it could prevent infection and promote healing. These practices were largely based on empirical observation and the plant's noticeable fragrance, which was associated with cleanliness and the repelling of insects.

However, direct scientific evidence supporting the efficacy of Southernwood for treating scratches and abrasions is limited. Some studies have identified antimicrobial and anti-inflammatory compounds in related Artemisia species, but there are very few controlled studies specifically examining Artemisia abrotanum for wound care, and none that confirm its effectiveness for this use in humans. As a result, the use of Southernwood for scratches and abrasions is primarily justified by traditional knowledge rather than robust modern scientific validation. Its rating reflects that, while traditional uses exist and may be supported by general properties of the genus, strong clinical evidence is lacking.
