About
Stephania japonica, known as snake vine, is a vine often seen in sheltered areas near the sea.
Safety
Protostephanine is an alkaloid collected from Stephania japonica. Antihypertensive agent.
Where it grows
In Australia, it is widespread vine seen as far south as Eden, New South Wales and north through Queensland. It is also found in Japan, India, Nepal, and many other areas of south-east Asia and the Pacific region. The original specimen was collected in Japan, hence the specific epithet “japonica”. The variety in New South Wales is known as bicolor, as the under-side of the leaf is somewhat paler than above.
