The NZ native stinging nettle (ongaonga) contains a yet to be identified neurotoxin, located in the spines (trichomes) of the leaves and stems of the plant, that causes loss of cutaneous sensation that lasts 3-5 days, persisting far beyond the duration of the stinging sensation. An accidental self-administration of the contents of a single trichome (~5 microlitres) provided an opportunity to study the effects of the toxin in a human subject in vivo. A crude extract of the plant has also been studied in vitro where it caused apoptosis of cerebral neurons and, at lower doses, inhibit neurite outgrowth. This long-lasting local anaesthetic effect has potential therapeutic benefit. To read more go to ‘Feeling the pain for the greater good‘ and Ongaonga could offer pain relief for Guillain-Barre’.
