<<Disclaimer: Verify this information before applying it to your situation.>> I had asked a question on reasons why some of us react to ginkgo bilboa - is it an allergy or cross-contimination or whatever. There was no answer to this question; however, I received two responses on how this herb has helped them. Summary follows: ...Mildie >I use Spring Valley brand of ginkgo bilboa. I have had positive results with using it. I have been using it for about 2 years. About 17 years ago my feet had a slight case of frost bite. When my feet would get the least bite cold they would itch and be uncomfortable. Since taking the ginkgo bilboa I no longer have any problem with my feet.< >I have used Ginko Biloba for the past 3 years. I am taking it to combat senility. I have been using both Nature's Way from Costco and Trader Darwins from Trader Joe's. Trader Joe's is a little cheaper and maybe not quite as effective. But either has greatly reduced the progress of my senility problems<
