About Urtica incisa Poir.
Urtica incisa, commonly known as scrub nettle, stinging nettle, and tall nettle, is an upright perennial herb. It is native to streams and rainforest habitats across eastern and southern Australia, ranging from north-eastern Queensland southwards through eastern New South Wales, then across southern Victoria, Tasmania, south-eastern South Australia, and parts of southern Western Australia. This species is also widespread across both the North and South Islands of New Zealand. According to the Queensland Poisons Information Centre, scrub nettle acts as a skin and eye irritant. Touching its stinging hairs with skin causes reddening, itching, swelling, and an intense burning sensation that can last for up to 36 hours. Indigenous Australians ate the leaves of this plant after baking them between hot stones. The leaves are considered a tasty vegetable, and colonists also used scrub nettle to make a tonic for "clearing the blood".
