Cultivation Details

Porophyllum ruderale is an annual plant found from the warm temperate zone of southern N. America and south through the tropical Americas to Bolivia and Peru. It is usually found in very freely draining soils, often in semi-arid regions where it grows after rains.
Requires a sunny position, succeeding in a range of soil types so long as they are well-drained.
In addition to being cultivated as a food crop, the subspecies macrocephalum is often found as a weed of waste and disturbed ground in its native habitat. It was introduced into the Galapagos as a food, where it has escaped from cultivation and is now classed as an invasive weed[

The aromatic oils, which are contained largely in the pores or glands that are especially plentiful on the leaves, produce a strong odour when the foliage is bruised, broken, or heated. Cures, real or fancied, that are attributed to various species of Porophyllum are probably largely due to either the soothing properties of the oils or the imagination by the patient that anything that is so odoriferous must be beneficial[

Higher antifungal activity is displayed when the complete essential oil is used, as opposed to individual components from the oil used in isolation, suggesting that enhancement of antifungal activity is obtained when other minor compounds are present in the oil, suggesting that the antifungal activity is a result of a synergistic effect.[
