so they took a malaria fighting plant and added ether to the method of extracting whats needed when obviously they didnt need to why? maybe the either is the reason for the mild side effects....

Metformin has common and extreme side effects. Usually, it makes people extremely nauseous. Those who can manage to keep it down experience other gastrointestinal distress as it works its way through your system. Some people (like me) experience dangerous side effects, such as uncontrollable extreme fatigue (sleeping 23 hours a day) and neuropathy in all four limbs at the same time. You have but to join a support group or two to see just how prevalent these dangerous side effects can be.

If a person eats garlic because they like the taste, it's a food stuff. If they eat it because they heard that it's good for their health it's a dietary supplement or medicine, subject to different regulation. Don't use an umbrella as a parasol, they have different classifications! Oh, but the word umbrella is derived from shade, so......

I tried atropine eyedrops, and my it dialated my eyes for five days. It was horrible, because I had to read the old CRT screen, and write, and the atropine made it hard to read, I had to look at the papers and computer monitor from a further distance. The eyedrops actually made me far sided temporarily. I also tried the 3 mg scopolamine patches that were for nausea, and I didn't have nausea. I had to put the patch behind my ear , for 3 days it sad to. I just had really vivid dreams, and I felt a little weird for those 3 days while I was smoking marijuana with the patch back then! I quit smoking weed 2 years ago.

DUDE!!!! Cannabis has some great properties! I've had epilepsy for 60 years, with violent severe seizures that broke bones (most recently, my skull and jaw), caused gashes that required stitches, and countless concussions. That was just the physical effect. Mentally, it would take me anywhere from 4 days to 3 weeks to recover, but I was having seizures at a rate of 2 or 3 per week, so I was rarely recovered before the next one hit. Two and a half years ago a friend recommended medical cannabis, and I tried it. I chose edibles, because the effects last longer. In 2 1/2 years, I've had 2 seizures, both so mild that I was recovered literally within minutes. If I hadn't had witnesses to both of them, I would never have known I had them. But after 60 years of seizures, other things developed, and I had also inherited bipilar disorder from my father. I had spent 62 years in a state of deep, crippling depression. My mother said I was a depressed kindergartener. For the last 2 1/2 years it's not just relieved: it's 100% GONE! I was born with a malformed vertabrae in my lower back, and I've been on opioids for most of the last 40 years. When I started cannabis, I reduced my dosages of opioids by 2/3rds, and with the help of cannabis, I'm able to skip the opioids for 2 days every 2 weeks to ensure that I'm not addicted. 40 years, with no addiction! Of course, all those concussions have resulted in frequent, severe migraines. The medication I take for that used to last 1 month. Now it lasts 3. Being bipolar has it's anxiety and panic attack issues, as well as social anxiety. I've even gone to the emergency room thinking I was having a heart attack, when it was a panic attack. Meeting new people often triggered severe attacks. Now I look forward to getting out and meeting new people. AG Jeff Sessions is dead wrong about "good people don't smoke marijuana"; some really GREAT people do! And he's dead wrong about it not having any medical value; it's medicine that has given me back my life at the age of 62, and I can't help but wonder what my life would've been like if I'd been allowed to have it when the seizures started....

You can't say that something is new and improved because if it's new there was nothing before that. If it's improved that's because there was something before the newer version that could be improved upon. You can however say that something is a new, improved product, clearly saying that an existing product has been improved in some way making it better than the original.

Diabetes type 2 is a disease of insulin resistance. To stop insulin resistance, you need to give your body a break from the hormone insulin. Insulin has two jobs: take blood sugar (fuel) out of the blood vessels and (1) put the fuel into the body's cells so that they can do their jobs (2) put excess fuel into the liver and the fat cells so that the excess fuel can be stored for when you have no food in your digestive system. When the digestive system has no food in it, blood sugar begins to decrease in the blood vessels. Then, the body's sensors sense the decrease and tell the pancreas to decrease insulin production and start producing the hormone glucagon. Glucagon's job is to take stored fuel out of the liver and the fat cells and put the fuel back into the blood vessels so that the body's cells can run on that fuel. Dr Jason Fung, MD, wrote the book "The Obesity Code", which explains about how insulin, glucagon, and other hormones effect diabetes type 2 and obesity.

Metformin inhibits thiamine from being properly absorbed into the body, which can cause neurological symptoms in the long run. Without thiamine, your mitochondria (aka, the energy source of your cells) cannot properly utilize other nutrients and oxygen in your body.

Feverfew and ginseng are another two great plants to mention. Feverfew is good at regulating migraines and ginseng is shown to have some (tentative) abilities to fight radiation poisoning. I also can’t help but think that some herbs were more for nutrition support than as medicine, the nettle species don’t have any easily identified active component but have high amounts of calcium, iron, and magnesium along with other vitamins, so maybe herbs like it were really better for eating and prevention than actual medicine

While travelling through Zimbabwe and Botswana (both still active with malaria), my grandmother made us drink tonic water the entire trip, which she said repels mosquitos; I'm not sure about the validity of that statement now, but I did report having far fewer mosquito bites, and the product we drank had quinine in it, so now I know my grandma wasn't just crazy.

Guys, cannabis isn't as life saving and powerful as these plants. These plants save lives, weed only fills an emotional hole with the emotional equivalent of empty calories for those who are depressed. What the heck were you guys smoking when you made these comments.
