Be ready for some graphic content—I can't write a review without getting a little graphic. I had a blockage that lasted more than a week almost three years ago. I think the germs from the stool that wouldn't pass backed up into my small intestine because I stopped eating. I've never properly digested food after that. Everything passes through too rapidly and emerges unsolidly. In the fall of this year, I became seriously ill with food poisoning. I cure everything myself because I can't afford to pay doctors, and I used a lot of natural remedies to eradicate every last trace of germs in my digestive system. Stools came out, of course, and they were almost water. I got them out of desperation because of the positive ratings. Four days after starting to take, the watery stools ceased. In eight or ten days, the stools were approaching the ideal consistency. I felt kind of normal, actually! After I ran out, I started to have somewhat looser stools once more, albeit not nearly as much as previously. I placed a new order, and things are now almost back to normal.


I often have Gastroesophageal reflux owing to hyperacidity anytime I eat acidic and sour foods. This brought me excruciating heart burns and burps after eating and chest pains. Sometimes I felt too tough to swallow when eating and that I was about to puke from sourness in my stomach. I occasionally feel that I’m having asthma. Very regularly, I felt that I was getting sleep deprived. It feels like if I’m having awful ulcers. I always felt that this was all related to stress but I always dispute it because even on easy going days things can happen to me. Due of this, I always tried to limit my eating choices. It made me get more aware with what I consume to keep healthy. And avoid heavy labor and stressful settings. This soreness continued to occurring more and more regularly as time goes on. I tried to locate medical attention and was offered drugs but got limited or no big effect at all. I was immediately encouraged to fully change my lifestyle and I did. But weeks go by, my conditions haven’t changed a m

My HVAC condensator leaked, which caused a terrible mess because it was below freezing for a spell. I bought this. When I used this, I was shocked to see that the leak seemed to be largely stopped. I turned off the equipment while the device was still in use and let it drain, albeit more slowly now that the silicone sealant was doing a decent job. I turned off the equipment and let it drain until it stopped, at which point I added more. As stated in the box, I let it stay for a full day. I went through the same procedure again because it spilled further up this time, applying it to any area that seemed suspect for a leak. Give it one more day to sit. After turning on the air conditioning, I noticed that there were no leaks left. I appreciate your amazing product and would use it once more as well as suggest it to others for leaks and other situations when a transparent sealant is required. Application Ease: Well, it was fairly simple, but since I'm absolutely not an expert at correcting things, it looked pretty bad. It didn't matter how it appeared, and I
