Take an aspirin
Prevent a heart attack?

Aspirin - The most common OTC (over the counter) drug.

Countless other drugs similar to aspirin are also popular.
Look at these yummy coatings used on Aspirin so you don't hurt your tummy?

Bayers coatings contain carnauba wax, corn starch, croscarmellose sodium, dextrose,FD&C Blue #1, FD&C Blue #2, hypromellose, lactose monohydrate, methacrylic acid copolymer, microcrystalline cellulose, polysorbate 80, powdered cellulose, propylene glycol, shellac, sodium lauryl sulphate, titanium dioxide, and triacetin. None of these ingredients is considered dangerous? 

How do they know this?  Oops I forgot they're FDA approved. Never mind

I'm only familiar with four of these ingredients and that's enough. Well actually, Blue #2 is a petroleum product as used in motors, gas tanks, asphalt, road Tar etc.

Carnauba wax - I just waxed my car with it. I've never thought about eating it. I never had a craving.

Corn starch - couldn't be too bad.

A personal favorite,  Propylene Glycol  It was used as anti-freeze in vehicles and I used it in cold plate systems in commercial refrigeration. 

My biggest favorite of all,  Shellac  Use it in my shop all the time. I noticed a long list of warnings on the can. It's very flammable and contains Ethanol. If swallowed, do not induce vomiting. Contact a physician or poison control immediately. Wonderful

We all should know by now there's a connection between Ethanol and cancers and a few other medical problems. However - not to worry. Our trusted FDA will likely have Bayer make changes to the aspirin coating formula in a decade or two. It probably takes a certain number of illnesses and deaths before any changes are made. I don't know what that number is.

Meanwhile, it's pounded into our heads that by taking an aspirin a day will help keep us from having a heart attack or stroke.  Oky Doky

I did a little test for fun.
I dissolved one 81mg (baby aspirin) in a small cup of water. I stuck a PH meter in it and not to my surprise the PH reading was around 3.0, very acidic.  About the same acidic content of the phosphoric acid in Diet Coke of about 2.6. This PH is actually a little more acidic than our normal stomach digestive acid. 

End
It has  been known since the mid 1930's that cancer thrives in an acidic environment. Americans use more prescription drugs than any developed country in the world, and,  more antacids.
 
And if you think Tylenol might do the trick, you had better do a little research. Tylenol contains  acetaminophen. 
It is found in numerous over the counter (otc) drugs. Said by many to be the No. 1 reason for liver failure.
But of course it's still on the market and approved by our FDA.
 
In 2017, the FDA issued warnings on aspirin and otc's containing aspirin. Some of the problems it can cause is scary.
 
But then, whose going to pay attention to me?  I'm not a talking head on TV and don't have a title like Doctor or PHd after my name.
 
Do your own research - It's your health. It's simple - just google  something like  warning label,  fda aspirin  and do a little reading.
