I came across a letter which reads as:
My 79 year old mom, who lives with me, suffered from a degenerative spine and knees. She read an article about the raisins several months ago, and we decided to give it a try. Prior to that, the routine was: out of bed, to a recliner with cold packs behind the back, Darvocet, then blood pressure meds and vitamins. After about 30-45 minutes, she could get up and walk around, with limited range and motion.
Two weeks of eating the gin-soaked raisins, she doesn’t need the cold pack and has even started a small garden. And, as a bonus, since the pain is all but gone, her blood pressure meds have been cut in half!

Procedure to prepare raisins:
Pour the gin over just till it covers the raisins. Yes, the golden raisins are the ones to use (for the person in Australia, maybe you can order them online). Leave the open bowl out on the counter until the raisins are plump with gin and the rest has evaporated. If there’s a little left in the bowl, just drink it. Put the raisins in a jar with a lid, not necessary to refrigerate them, but it won’t hurt them if you do. The alcohol is a natural preservative.
Dosage: Take 9 (nine) raisins each day, in the morning.
