I started using black cherry juice, one cup a day, back two years ago. I can't take arthritis meds so I was desperate. It took about two months for me to realize that something was working. The cherry juice reduced swelling and, consequently, reduced pain! I make sure to drink it very slowly and on an empty stomach since I am convinced that it works best that way. It's too bad that most people just look at me like I'm nuts when I try to get them to drink cherry juice and quit their meds. There are times although when I might strain a muscle exercising and I take a pain reliever but only on rare occasion.
Drinking cherry juice before bedtime puts me to sleep also! I can feel myself relax and fall asleep much faster without medications.
My mother has tried various things to treat Arthritis but nothing worked well enough till she heard from someone else that 6 cherries a day works to fix it. (I have heard cherries are effective at fixing gout too) She tried it with near perfect success, she has to keep taking them but as long as she does she is pain free.
She has told other people and they have had success.
It was noticed that my aging cat was no longer willing to jump up on the arm of my chair and would take longer to get up in the morning, it is defiantly arthritis. So I mushed up some cherries into hit cat food which he happily ate and after a week he was freer and freer and found it easier and easier to jump up.
While fresh organic cherries are obviously the healthiest canned or bottled cherries and the surrounding cherry juice works fine even with the added sugar and is cheaper and can be obtained year round without great expense.
I have also heard of someone who took 1 tsp of Turmeric a day for 5 days and wiped out their Arthritis for good.
But I must give Cherries the highest marks for being enjoyable, amazingly effective and cheap/easy.
