Description

Aristolochia acuminata (better known by its ‘old name’ A. tagala) or Akar ketola hutan in Malay is characterised by its oval lamina with a deeply heart-shaped base, a perianth with a globular flask-shaped base (utricle) that narrows into a funnel-shaped limb with a tongue-like lobe. Its fruit is a papery capsule that splits from the stalk into 6 valves when mature and hangs like an inverted parachute. The winged seeds are dispersed by wind.

The Birdwing butterflies (Papilionidae) are attracted to lay their eggs on aristolochiaceous plants due to their aristolochic acids sequestration habit (Nishida et al, 1993). The caterpillars feed exclusively on Aristolochiaceae plants. They sequestrate the poisonous aristolochic acids without being poisoned themselves. This habit plays an important role in chemical defence against predation, and hence maintaining the host fidelity (Weintraub, 1995).

Besides its important ecological role as a food plant for Birdwing butterflies, Akar ketola hutan was used in traditional medicine. The leaves are pounded and applied to the head for fever (Burkill, 1966). Recent studies have confirmed that aristolochic acids or their derivatives found in Aristolochia species have several adverse effects on human health and of several animal species (Kiew, 1999). A ban on aristolochic acids in traditional herbal preparations has been enforced in several countries.
