Several years ago I was having numbness/pain in my hands and feet, especially upon waking. It was very uncomfortable. I went to my doctor who said it was neuropathy. He offered pain meds and that was it. I did some research and found out that Burdock Root can help with that. I took three 00 capsules (that I made myself out of Burdock Root Powder I bought in bulk) three times a day. (5' 5'' and 125 lbs. ) Within a couple of weeks it was healed. You are supposed to take Burdock Root for at least three months when you take it. (I probably took it for at least 6 months. ) It is a blood purifier. It is a very safe herb - it is use for food in some cultures. This problem has never returned. I should add that I keep a pretty healthy diet, avoid MSG and artificial sweeteners and ingredients, drink lots of water, etc. If this were to happen again I would add 2 T. of Blackstrap Molasses a day as it is so high in nutrients and good for so many things.
I had very painful neuropathy a few years ago. My doctor offered me pain meds and that was all he could offer. I read about Burdock Root being helpful for it. I took 3 capsules 3x a day. It can take a while for it to work but for me I was improving a lot in a week or two. It is recommended that you take Burdock for 3 months to maximize the effect. I took it for at least 6 months. This was several years ago and the problem did not return.
Burdock Root cleanses the blood. It is a vegetable, it is not dangerous to take this.
