While many over-the-counter and prescription drugs are made out of nice, normal ingredients like willow bark (aspirin), burnt seaweed (iodine) and poppy sap (morphine), we found some others made out of the most disgusting, awful crap on earth.

Take your standard blood thinner, for example. It's a little cocktail the docs call heparin. And what's heparin made out of?

Pig bowels.

OK, let's be fair, not all heparin is made out of pig bowels ... some of it is made out of cow lungs.

But wait, it gets better ...

Sometimes a doctor will give you too much heparin -- they're only human, after all. So what do they do to counteract the heparin and keep your blood from oozing out of your skin? They give you protamine sulfate ...

... which comes from shark semen.

Dead in Hours ... or Pain Free!
Don't get severe neuropathic pain. Aside from the hideous pain itself, it might just tempt a doctor to stick a needle in your spine with the latest painkiller, ziconotide.

The good news: Ziconotide works. Sure, there can be some ghastly side-effects ... like a doctor shoving a needle into your spine ... but it works. And unlike morphine, you probably won't get hooked on it.

Now the bad news: Ziconotide wasn't neatly created in a lab. It was derived from the cone snail, a slimy gastropod with harpoon-like teeth and a sac full of toxin. So the price for pain relief it seems is cone snail slime sliding around your vertebrae.

This Tastes Like ...
Premarin used to be a wonder drug -- the first hormone replacement treatment for menopausal women. When menopause hits, the female hormone system powers down, leading to massive emotional and physical symptoms for many women. It was a banner day when the medical establishment stopped ignoring the condition and finally tried to treat it.

But dear God, look at the treatment: Replacing those natural hormones with artificial ones synthesized from pregnant-mare urine.

Imagine 10,000 white-coated lab assistants standing in front of stables with horse-size beer funnels and giant pee buckets ...

Modern technology has finally caught up with the Premarin bandits. It turns out we can compound replacement hormones from sources like soybeans. But there are still doctors out there prescribing Premarin. And until the last pregnant mare can take a leak in peace, none of us are truly free.
