So, based on the paper I previously posted, I devised a deworming regimen.
60 g of dried Artemisia absynthium, pulverized. Boil 300 ml of water. They used distilled water in the paper but regular tap water will normally do just fine. Once the boiling point is reached, put the plant powder in a flask and add the boiling water to it. Let it sit at room temperature for 72 hours, agitate the mixture ocasionally. I revommend wrapping your flask in aluminum foil against photoreactions within the solution. After this, pass it through a coffee filter and drink it in one go, empty stomach. This has to be repeated for three day in a row, so prepare a new, fresh batch everyday.
Now, for the 🚨WARNING🚨:
This could potentially extract about 125 mg of thujone in your 300 ml aqeous solution. This is >415 mg/l thujone. The EU has an upper limit of 35 mg/kg thujone in alcoholic beverages. While thujone is one of the many active compounds probably also responsible for its antithelmic properties, this can hurt you. Spasms, nausea, kidney andliver failure. Wikipedia says that dosing ethanol beforehand can mitigate this (a.k.a. just drink some vodka or other hard liquor). However I'm currently too uncertain about this to even try it myself. I've found out there are low-thujone cultivars bred specifically for consumption, so this could also be an option. In any case wild specimen can vary a lot on thujone concentrations.
Trevor Goodchild:pondering_orb: (npub1cka…4wty) do you have anything to add here? You seem to know a lot about biochemistry and I'd like a second opinion
