Comptonia peregrina
Aromatic shrub of eastern North American dry woods; used by many Indigenous peoples for diarrhea, wound healing and insect repellent.
Sweet Fern (Comptonia peregrina) is an aromatic shrub native to eastern North America, traditionally used by Indigenous peoples for diarrhea, wound healing, and as an insect repellent. Its primary active compounds include myricadiol, catechins, tannins, essential oils, and flavonoids, which contribute to its astringent, anti-inflammatory, and antimicrobial properties. Modern evidence supports its use as a topical wound healer and insect repellent, though clinical data remain limited.
The astringent and anti-diarrheal effects are attributed to tannins and catechins, which bind to proteins in the gut mucosa, reducing permeability and fluid loss. Myricadiol and flavonoids exhibit anti-inflammatory activity by inhibiting cyclooxygenase (COX) and lipoxygenase (LOX) pathways, thereby reducing prostaglandin and leukotriene synthesis. The essential oils, particularly monoterpenes, act as insect repellents by interfering with insect olfactory receptors. Additionally, the plant's antimicrobial properties are due to phenolic compounds disrupting bacterial cell membranes.
