Of course they work....there's TONS of drugs in them.
It varies by brand but most of them have opiates in them. There are also hallucinogens, sleeping aids, and euphorics mixed in.
You know...I know people love "natural" things (& I'm a Whole Foods addict, with chickens, & I trade eggs for my neighbors honey, etc. so I'm right there), BUT I wish people would understand that most of the Rx only drugs COME FROM PLANTS. Some are synthetics, but I could whip up a batch of heroine or morphine (just tick the box), from the opium gathered from poppies. For some less accurate pain killing just use the sap straight, doesn't even need to be boiled.
Then there is the nerve toxin found in belladonna (deadly nightshade). It's useful as a numbing agent in very small doses (like what is found in Hylands Teething tablets), but it DOES actually have side effects. Go ahead. Figure out the doseage for YOUR weight and munch them. But make sure someone is standing by to call 911. You're going to start feeling very happy, will start to lose conscious control over parts of your body (sometimes this includes bladder control), and are going to start seeing some very strange things. In my honest opinion it's better to do whiskey & sugar on a baby's gums then use teething tablets. Of course, that would go against my own personal code, but not as much as getting them high.
::Sigh:: I'm sorry. My cousin is not only a pharmacist, but also has her naturopathic MD with a focus in herbal pharmacology (of which I've only taken classes). One of the things the profs did was to have them test out things on themselves, to help them understand just HOW POWERFUL many of these medicines are...and how different preparations change either the acting ingredient, or the strength of the medicine, etc. Amongst many many other things. So in addition to my own classes, guess who got to help my cousin in her lab work?
So I am sorry. Herbal & Natural do NOT usually mean gentle. Rattlesnake venom and death cap mushrooms are natural. Deadly nightshade and datura are herbal. The FDA has soooo many thing wrong with it, that I'm more inclined to add a swear word before their name ;), BUT the business weasles making money hand over fist by selling all of these soooooo non regulated medicines ... I trust far far far less.
Teething tablets DO work. But if you're seriously trying to avoid drugs...stick with ibuprofen, or tylenol. Or...if you're not afraid of asprin, go for the boiled inner bark of the white willow tree to extract the acetylsalicylic acid (asprin).
Don't get me wrong...herbal pharmacology is AMAZING...and I'm a huge proponent of it. Western medicine only uses a tiny tiny fraction of what is available...and the drug companies create some major roadblocks, but it IS medicine. And, like ALL medicines, dangerous...even deadly if misused. Which is darnably easy, especially these days with bottles and bottles of the stuff concocted with little understanding and thrown up on the shelves in order to make a quick buck.
All my best,
