[quote=”Peter Finke” post=2938]The only efficient medicine we know of is 2-amino-5-nitrothiazol, a yellow power, which was sold as “Hexa-Ex” (by Tetra) or Spirohexol (by JBL) in a pressed solid form.[/quote]
97% pure 2-amino-5-nitrothiazole powder is available from sigma aldrich in the UK and perhaps other scientific suppliers elsewhere –

Perhaps someone might be interested in purchasing and dissembling a quantity. I have not checked postage costs or any restrictions that may be in place.
There also appear to be several retailer sin the UK and Ireland still selling Spirohexol tablets –
