I have done a bit more checking. This Chronic Wasting Syndrome is usually caused by poor water quailty and is easlily transfered to humans. Perhaps I should try and catch it? might be a good diet apart from the death part.
Most recomended treatment is Metronidazole so you may need to sweet talk your vet.
It doesnt matter to much if the garlic is freshly dug up or store bought.
Fresh garlic doesn’t smell much at all. When it is crushed or juiced a chemical reaction happens, that is why the smell gets so powerful so quickly after cutting it.
It takes about 5 minutes for the reaction to peak and lasts around an hour before slowly fading. After this the garlic looses it potency as a de-wormer.
The smell stays for a while and it still useful as an attractant to entice fish to feed.
Tablets, crushed, pre processed and mixed into frozen food mix garlic will still work to fix internal problems but only at a small % of how good it is when fresh.
