I had suffered knee injuries most of my life starting when I was a lean, athletic teenager. I started jogging with a friend who was on her school track team. The most I could do was 25 minutes till my knees would start to hurt. After one week I had to stop jogging to be able to continue my regular daily routine. Every so often I would try to start jogging again and the same thing would happen. Then as time went on I figured out what to avoid to keep from getting knee injuries most of the time and they only happened about every 5 years. It would happen that I would get a major knee injury that was debilitating to me. The knees would alternate. I resorted to bicycling most of my life and that eliminated most problems. Once I got into my 50's I ended up having another one of those ""major"" knee injuries so that I was hardly able to walk for a few days and had to baby the knee for several weeks. I learned about the benefits of Eucommia Bark and started taking it and in a few days I saw a decrease in pain. I was so careful now, as bicycling and jumping or jogging on my trampoline had been the only things I could do strenuously and not have it affect my knees, but now even these 2 activities caused my knees to hurt enough to have to take days off from workouts. I persisted with taking the Eucommia Bark and after a few months I was able to resume normal intensity on my trampoline or bicycle just for shorter periods of time. I did not like the limits but figured I had to give my body time to recover from all the knee injuries I had had in my life. Fast-forward to 2 years of taking Eucommia Bark and I am pain free with no knee problems. Fast-forward to 3 years on Eucommia Bark and I am able to do anything again! I even started speed walking first for 1 hour, then for 2 and sometimes 2-1/2. The only time I had any soreness was in the first week, at which time I used Helychrisum Essential Oil on my knees. It has the highlest frequency of essential oils for fighting inflammation and it helped me get past all the soreness till the Eucommia Bark could build up my joints better. Over the next few months I have had occasions to jog on nature paths for an hour and a little more with no pain and no down time! What an amazing herb God has given us in Eucommia Bark to build up our joints' cushioning!
