Tiger's blood! One of Charlie Sheen's doctors was so confident that he could cure the actor of HIV that he actually injected himself with Charlie's tainted blood.

The shocking reveal came during an interview with Dr. Oz in which the former "Two and a Half" men star said he traveled to Mexico to meet a man named Dr. Samir Chachoua, a man who claims to know the cure for cancer and AIDS.

While in Mexico Charlie underwent a succession of injections recommended by Dr. Chachoua, who is not licensed to practice in the United States.

"We did see some incredible results early on," Charlie said. "Off the med cocktail (a mix of antiviral HIV medications) that I was undetectable. And it stayed that way. I did an experiment I didn't have any faith in but I went along with it."

It was then that the doctor became so confident in his abilities that he injected Charlie's blood in his own body, something that Dr. Oz called "pretty inappropriate."

"Inappropriate and completely mind-blowing," Sheen said in agreement. "I watched that happen when he felt so confident. He delivered that my blood would not be any risk to him."

Shortly after revealing publicly that he is HIV positive, Charlie vowed to fight it and try everything necessary, including experimental treatments.

"I didn't see it as Russian Roulette," Charlie said. "I didn't see it as a complete dismissal of the conventional course that we had been on. I'm not recommending that anybody else do this. I'm presenting myself as some kind of a guinea pig."

The treatment, it appears, didn't work.

Just before the show, Charlie got an upsetting update on his health.

"I'm a little off my game because right before I walked out here, I got some results I was disappointed about," he said. "I had been non-detectable, non-detectable and checking the blood every week and then found out the numbers are back up."

Hence, he's said he'll get back on his anti-viral HIV medications immediately.

"I'm going to take them on the flight home," he told Oz. "What am I, an idiot?"

The Oz interview is part of series that Charlie is participating in. In a previous segment of the chat, he said that he is surprised to be alive following his HIV diagnosis.
