My personal "cures" that work better than any expensive "treatment":
REPEL SPORTSMAN STICK (deet), stopped my rosacea by repelling the demodex mites that cause rosacea. Start salicylic acid face wash a week or so after starting repellent, cause salicylic acid KILLS the mites, may initially "pimple" the face if used first. It is the bacteria from the mites that cause rosacea. Mites prefer human cheeks, chin, and nose. NEEM OIL (natural, and smelly)may work as well, but I could not bare the strong scent
FOLDED BLANKETS AND REGULAR PILLOWS can elevate the head and chest, relieving pressure on the throat, brought on by a thick neck (16.5"+). If one wears an OTC snoring device, and still snore, it is likely one has a thick neck, and this elevation can improve breathing.
For years I had migraines at least twice/mo. lasting 3 days each. Finally I found taking one feverfew , and one fish oil capsule per day STOPPED all my migraines. This was not my invention, as feverfew has been for migraines for at least 20 years. However, for me, it proved to be incredible results.
I use SUPER GLUE FOR CUTS AND BURNS. It NEVER stings, seals the wound, and keeps out bacteria. Great for my burns, and often prevents a blister. Because the burnt skin is no longer a bacteria barrier, white blood cells have to kill bacteria, forming a blister. (The only difference between super glue and what doctors use is one molecule that lets medical glue be flexible.)
1MHZ ULTRASOUND (devices with 2" heads that sell for about $35, just not for sale on the main selling sites, try Aliexpress from China, usually arrives in 2 weeks) can vanish a deep bruise in one day with one 15 minute treatment. 1mhz can penetrate 1.5" into the skin. Also works great for headaches, and any healing. Gel required.
Want fresher breath? Brush your teeth WITHOUT toothpaste...just water. From my experience, there is something in toothpaste, that actually makes my breath worse in the morning.
Okay, COLLAGEN, ANTI-GRAY, AND BIOTIN are touted for skin and nails, but they actually work. I am 62, have no wrinkles, and no gray hair any more. My hair is shiny, like young hair. No more kinky over-shiny white hairs. No straw-like hair from peroxide coloring.
Sure, I have many inventions that cure other things: a Ladder Lackey to prevent ladder accidents that also lets one access places other ladders can't reach.
And, I have 5-star children's books.
