Mechanism2
Two different but related theories have been proposed for the mechanism by which picrotoxin acts on synapses. (wikipedia.org)

In view of these facts it is surprising that only a few native plants have been commercially exploited. (medicinalplants.us)
Found3
Under kinetically controlled conditions, this process generally results in exo cyclization and forms bridged ring systems like those found in picrotoxin. (wikipedia.org)
To round off this paper we have included a list of compounds found in New Zealand plants of actual or potential value in pharmacy. (medicinalplants.us)
In the final part of this paper we propose to review briefly those plants and chemical substances found in them which appear to be of potential value in chemotherapy. (medicinalplants.us)

White2
Indeed some authorities on Maori culture believe that all medicinal use of plants by the natives was learned from the white man's example - a conclusion which seems contrary to the observations of Captain Cook and other early visitors to New Zealand. (medicinalplants.us)
Other students of the Maori suggest that pre-European use of plants was external, e.g., in vapor baths and embrocations, and that the natives extended the use of these herbs after the pakeha (white man) arrived. (medicinalplants.us)
