Sorry to get al serious on you.
This article has some info about research on
Developing novel anthelmintics from plant cysteine proteinases https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2559997/ its rather dry reading
Here is a sample "There have been considerable efforts to identify the active ingredients and indeed some are well known [
30-
32], but, to a large extent, few have lived up to their expectations when tested rigorously [
33], and even fewer have been found to have curative properties that can compete effectively with synthetic drugs"
And another "Some of the earliest known medicinal anthelmintic plants include papaya (
Carica papaya), figs (
Ficus spp.) and pineapple (
Ananas comosus). Anecdotal reports of their usage for the treatment of worm infections by the native inhabitants of Panama and South America stretch back to over a century ago [
40]. Their extracts were shown to be highly effective in clearing the most obstinate of human intestinal worms,
Trichuris trichiura, in the 1920s [
41] and more effectively than any of the current synthetic drugs [
42]. Indeed, European doctors used papain and papaya latex for the treatment of worms in the 19th century [[
43,
44] and see later in this review] but, it was not until the 1930s that they were shown to be actually capable of digesting nematodes [
40] and their enzymic basis was discovered [
45]. The active principles are now known to be cysteine proteinases (CP) that occur naturally in various parts of the plant, and Table
Table11summarises some of those known to be contained within plants. For example, in pineapples, different combinations of enzymes occur in the stem, and in the fruit. The latex of both papaya and figs contains CPs.
