Back around 1978 to late 1980's my knees hurt when I had to kneel to work on any heavy equipment. The pain was so intense I had to support myself for a little while using my arms to hold me up.
My wife worked with a woman of Dutch heritage. They were talking about husbands other stuff women talk about. My wife mentioned my knee pain problem. The woman said to get a bottle of Gin & a box of golden raisins. Instruction was to soak the raisins for about a month in the gin then take a tablespoon full once a day of the brandy like mix. I figured it couldn't hurt to try, mostly because I like gin, raisins & a good brandy.
I don't know how long it took but the pain went away. Maybe a year after I noticed the pain was no longer there I stopped the mixing. Probably early 1990 was when I stopped & I haven't had any pain since. Moving to the dry southwest was part of our plan to try to minimize arthritic pain. Arthritic pain free & age 80 knock on wood that it continues.
I looked up the gin & raisin formula to see if it was a real thing or just my mind fooling my body. This web site explains the reason but presents the use a different way.
