This species containes aristolochic acid, which is known to have toxic side effects in larger doses. Acute toxic manifestations are tachycardia, increased respiratory rate, ataxia, sedation and marked vasodilation.

Cultivation Details
Prefers a well-drained, humus-rich, loamy soil and a position in full sun or partial shade[2]. The flowers of many species in this genus form an intricate trap for pollinating insects. The insects are tempted to an area of the flower where they are unable to grip and they slide down into the utricle - downward pointing hairs prevent them climbing out[2]. The trap helps to ensure the fertilization of the flowers and the insects are eventually released[2].
Propagation
Seed - pre-soak for 48 hours in warm water and surface sow Germinates best at a temperature of 25 - 30°c[2]. Softwood cuttings[2]. Cite as: Tropical Plants Database, Ken Fern. tropical.theferns.info. 2026-02-19. <tropical.theferns.info/viewtropical.php?id=Aristolochia+acuminata>
