★★★★☆
The first natural product/supplement that I tried for peripheral neuropathy (caused by oxaliplatin in chemotherapy) was grapeseed oil and then grapeseed extract in a caplet form with excellent results that allowed me to reduce the amount of hydro morph contin that I was taking by about 40%.
I have told others about it and most that tried the liquid form had stomach upset from it.
I use 50-100 mg three times per day.
