Costus comosus is an uncommon plant in Western herbalist notebooks, its uses belonging mainly to quiet, local traditions. Its flowers are reported to have been used occasionally to help with digestion, though this practice was never passed down as widely as for other more common plants. Caution and restraint therefore remain in order with a plant that is still poorly documented.
The flowers were reportedly traditionally used as a light preparation to help with difficult digestion, according to loosely formalized local uses.
Certain practices report an occasional use of the infused flowers to ease a feeling of heaviness after a meal.
The plant was reportedly used occasionally in certain local North American traditions, though its precise uses are not widely recorded.
In the absence of sufficient data on toxicity and possible interactions, the use of this plant should only happen under the advice of a health professional or a qualified herbalist. Discouraged for pregnant or breastfeeding women, for lack of available safety data. Do not give to children in the absence of specific data. Avoid any prolonged or high-dose self-medication, as this plant is poorly documented in Western traditional literature.
