DMSO thins the blood, naturally. Way better than warfarin or coumadin. There are books on it by Naturopathic doctors and such, attesting to its healing qualities. Here is my experience:
Had a hard fall mostly on my shin, it hurt but I got up by myself and walked away as I had errands to do. Got home 2 hrs later, noticed my leg didn't hurt anymore and was surprised to see it had swollen to 1.5x its size! I did icepacks, elevation & acv/epsom salt soaks. I also applied DMSO 4x a day.
About a week later I was on a flight sitting beside a doctor, still swollen. He thought it could be DVT related and told me to see a Dr. Not wanting to take warfarin or coumadin, I stepped up the DMSO (rubbed on leg only) to every 2 hrs, and arranged to drink 3 or 4 750ml bottles of water one afternoon/night, and the next day my leg was back to almost-normal.
I have a good lymph system, I've been told. I wanted to open the dam sluices and get that excess water out! I peed alot that night. Only I could tell there was still a little swelling left at the ankle, which was gone soon after. I boarded my next flight the next day with no problem with my leg.
I haven't seen DMSO mentioned as a blood thinner, so I wanted to mention it is worth asking a Naturopath about and looking into on your own.
Best of Healing, everyone.
