But it must be raw apple cider vinegar with the mother. In the us it is available at health food stores and in the health food sections of supermarkets generally under the brand name of braggs or spectrum or get it online.
take about an inch to inch and a half in a glass and fill the 8-10 ounce glass after that with clean water.
I add raw honey or sea salt to improve taste and the honey enhances it.
See the great book by the guy who popularized apple cider vinegar in his book vermont folk medicine book on arthritis...j c Jarvis. It is called arthritis and folk medicine

It is amazing on how he treated arthritis with acv and is worth reading.
Also try herbal tinctures (not capsules) in organic form of things like yucca, devil's claw or boswellia
Here are some of them

Also a vegetarian or vegan diet has helped arthritis. A diet like the hallelujah diet or even 100% raw has cured it. see testimonies at hacres.com and also see what is the hallelujah diet to see what foods are considered raw (more than one expects). A whole food, vegan, all or mainly raw diet should definitely help, but some got better on just a vegetarian diet as the meat fibers have something to do with leaky gut syndrome which contributes to arthritis I read once.
the only safe vinegar to use in or on the body are raw vinegar apple cider and wine can be raw but one usually used raw apple cider vinegar (acv) at least three times a day.
the reason it works is see in Jarvis' experiments (he was a human and animal doctor) on cows. Comparing the two groups of cattle one feed the acv and one not. those feed acv had easy to cu through arteries and flesh and hard to cut through bones while those not given acv had hard to cut flesh and arteries and soft bones.
This is cause the vinegar causes the calcium to not circulate so much in the blood and lead to harder flesh and hardened arteries but go to the bones where it belongs..this is why they hard easy to cut arteries and hard to cut bones. Those not getting it the calcium remained in the flesh toughening it and soft bones as the calcium deposits went to joints and not the bones causing osteoporosis (too much protein also causes osteoporosis). It is why they use vinegar in vermont where the water is hard to dissolve calcium on the tea kettles and in the holy heater and why vinegar dissolves egg shells leaving behind just the membranes.
Also a good anti-inflammatory herb is turmeric see holisticonline site linked above and search for anti-inflammatory herbs for more. Be careful using nsaids drugs they caused permanent kidney damage in my mom who wound up on dialysis which increases heart attacks 30 times and ruins the quality of one's life and caused her to have 9 heart attacks in one year when she never had heart disease and the last killed her. She took Motrin daily and they said that is what damaged her kidneys.
Hope this helps
