I bought a cheap brand but it seems to help. Need to take it regularly for more time before I make a final evaluation.
I bought 21st Centruy herbal extract horse Chestnut seed extract. It was about $5. I take two caps which is 600mg. I also take 2 caps each of Food-Zyme, Calcium d-glucarate, and DIM (diindolymethane). I take the last two because they are supposed to be good for autoimmune diseases and cancer. The last two are phytonutrients. I try to take this amount each morning and evening but forget from time to time.
I plan to start taking Food Grade Diatomaceous Earth (must be food grade because swimming pool stuff is poisonous). Not only does it clean out the colon but also sweeps the arteries and veins. The best information is from "Wolf Creek":http://wolfcreekranch1.tripod.com/defaq.html
Today, Nov 5, 2011, I have have real feet with no swelling. When I pinch about two inches above the wrist, I still have edema but greatly improved.
I should warn you that when the swelling started going down, I spent the night and next day "to and from" the bathroom.
In doing more internet research, it appears that swimming (and no other exercise) helps reduce the swelling. Not having access to a pool, I cannot try it. But it would be nice to hear from somebody else who tried it.
