I tried to summarize the excellent postings of this thread as follows:
1)Recent research (15 Nov 2007) discovers a novel peptide which blocks a toxic protein, NF-kB and in this way protects neurons, normalizes neurotransmitter levels, and improves motor functions in mice with PD.
2)1995 research results indicate that curcumin inhibits NF-kappa B activation
3)Nutr Cancer. 2007;57(1):78-87 :Zyflamend, a polyherbal preparation, inhibits invasion, suppresses osteoclastogenesis, and potentiates apoptosis through down-regulation of NF-kappa B activation and NF-kappa B-regulated gene products.
When I last visited my PD specialist few months back he “assured” there is nothing which can slow down PD ! I am sure he is too busy to follow up research such as above.
By the way, and based on other Google search, I have been adding a spoonful of tumeric to my dish even though my wife complains that I am spoiling the delicate taste of her cooking !
