But on the subject of herbs especially regarding neuropathy, one needs to know the following.
Herbs cannot be taken in some cases with certain medications. You need to check with your pharmacist to see if the herbs and your medications are compatible. Pharmacists have a database that they can check.
As an example: There are no clinical trials showing that any herb can help repair the nerve damage that is neuropathy. Nor can it build healthy nerves. They do have some value in increasing blood flow, or calming the body, but not in the actual repair of the nerve which is what causes the neuropathy symptoms.
There are many products being advertised as helping neuropathy with 4 or 5 different herbs extracts in them. It is questionable whether they have been tested together, and since there are no trials regarding neuropathy, questionable as to whether they will help or not.
A number of herbs taken together often causes stomach problems, such as heart burn. They can create more problems.
Check out all the herbs in a formula. Remember, this is not like a herb tea, made by boiling the herb leaves, or sprinkled in your salad. These are herb extracts in much more potent amounts then found in nature.
