In my kitchen yesterday. I measured out the crushed tablet. 62mg, which comprises 30mg Ginkgo and 32mg binding agent. I had been tipping the tiny bits into a glass of water and swallowing. 3 of this on dose day. Instead, I chewed those tiny bits.
I am now accustomed to a slight rise in tinnitus intensity on dose day. This I put up with as I get a lowering of tinnitus on day 2, day 3 or both. The rise in intensity will come on sometime after taking the (now discontinued) 30mg Ginkgo tablet. Yesterday on chewing, it came on almost instantaneously. Clearly the Ginkgo is entering the bloodstream via the mouth.
Which leaves a thought. This is the original way Ginkgo was taken. Chewing the leaf. With the sophistication of tablet form, it will enter the bloodstream probably somewhere in the bowel. Having been subject to stomach acids to break the tablet down. One is left wondering if such acid involvement is a good idea regarding Ginkgo's action. Anyway, there it is. I might just have hit on something when it comes to why Ginkgo has no effect for so many, other than a suspicion that the doses we take, above 100mg in one day, every day, is just too high.
