I read a study of curcumin being given to mice with cardiomegaly as part of congestive heart failure and the curcumin REVERSED the cardiomegaly. It will take the usual forever for them to finally get the human trials done and proper dosages established. In the meantime, my little miniature pinscher dog was given less than a month to live as his heart was so enlarged it had filled his upper chest. He also was drowning with fluid in his lungs. He had the terrible constant congestive heart failure cough as well. As there is really no treatment besides diuretics, I researched curcumin, found out that in most cases it relieves gastric problems (which he also had) as long as the dosage isn't more than it should be, and that Doctors Best Curcumin with BioPerine was the best product out there for a supplement. I had no idea of dosage, and started giving my 4 pound dog (miniature pinscher) 5 capsules a day mixed in with his wet dog food. I gradually raised it to 7 capsules with no ill effects. It has a mild peppery taste, but for the most part older dogs can't smell or taste food well anyway, so he liked me adding a little bit more spice to his food. It took a month, but his cough gradually subsided and then went away. A year went by. I ran out of money and stopped giving him the curcumin. There was a "grace period: of about 2 months and then the cough came back. I thought I'd just about killed him and there would be no more reversals. Wrong. Restarting the pills worked the same as the first time. Same thing happened the next year when I stopped the curcumin. The following 2 years as well. My dog will be 17 in one month. He has lived FOUR YEARS after being in the last stages of congestive heart failure. For those who need tangible proof, the best I can give you is that the dog's name is Bruno, a miniature pinscher, his vet is Dr. Wishnack in Poway Animal Emergency Hospital, and I have the four year old x-rays that show how bad he was. He was brought in to them on New Years Eve four years ago, totally limp in my arms. They brought him back that night, but the prognosis was he'd be gone sometime soon within the month. I have not gotten new x-rays to see what the internal physical changes are because I don't have the money. But I have everyone in my household as well as visiting family and friends who have seen the visible proof over four years that the congestive heart failure symptoms disappear when my dog is on a regular schedule of curcumin, and that they slowly come back when I stop giving it to him. I don't know what the dosage would be for other dogs or for humans for that matter. My trial and error method for dosing him was to see how much I could give him without gastric upset. He's 4 pounds and he takes seven capsules emptied into his food. I don't know if he could take less with the same effect, but I don't want to jinx it so I'll continue giving him the seven capsules. There doesn't seem to be any listed severe side effects from it, other than too much will give them a tummy ache, and there will be bright yellow poop.that can stain stuff. I've not seen any side effects from it with Bruno. In fact, the curcumin has another benefit. He always had gastric problems. In the x-rays he's had over the years, his stomach was always extended with a lot of gas, and when he ate the gas literally would be pushed out while food was coming in. With the curcumin, that doesn't happen. The only time the excess gas starts coming back is when the curcumin is stopped. His appetite was bad before, probably because of gas pain, and he was always trying to eat grass. Now he has a hearty appetite, and it seems like there are no gastric problems at all. Anyways. It works on mice. It works on a dog. Maybe it will also work on a human. That I can't tell you because I don't have any human "guinea pigs" to try it on. But I can tell you that if your dog has been diagnosed with congestive heart failure, put them on the Doctor's Best curcumin with BioPerine. Read more
