Traditional uses
Relief of digestive troubles
The leaves were traditionally infused to relieve stomach pain, bloating, and mild digestive troubles in Andean communities.
External use against joint pain
As a poultice or rub, crushed or warmed leaves were applied to painful joints and areas affected by rheumatism.
A traditional repellent against parasites
Marco has long been used in rural households as a repellent against certain parasites, both for domestic use and in the care of livestock.
Traditional care for minor wounds
Crushed leaves, or as a decoction, were sometimes used as a wash or compress to clean superficial wounds, according to local popular usages.
What to know before use
A plant reputed to be toxic at high doses or with prolonged use: professional advice is essential before any internal use. Strictly not recommended during pregnancy and breastfeeding, due to a traditional abortifacient use reported in certain regions. Keep out of reach of children; do not use in young children. Avoid any prolonged internal use without supervision, as interactions and skin sensitization (Asteraceae family) are possible.
