OK, done. That was untrue. Water does not "cluster". Shui Yin Lo is a quack who claimed to have made room temperature ice.
I haven't had one, but I've had younger siblings. It may seem like it, but they don't actually cry 24 hours a day. They will stop at some point.

So a burn left untreated will stop hurting as quickly as it will if treated with calendula? Do a little experiment on your own and find out.

And maybe read this.

A quick Googling reveals calendula to be an ointment with an actual herbal component. I don't know about it in particular, but it is at least possible for herbal remedies to work, as they actually have ingredients, and many medicines are derived from plants. Herbal remedies (the ones that actually work) don't rely on "vibrations" or "clustering", they are essentially weak versions of the actual medications that are derived from them.
I know what natural frequency and natural resonance are.

Natural resonance is irrelevant to the concept of homeopathy. It is based on a real vibration, not "vibration" or water "clusters".
When they say vibration here, they are talking about actual, physical, left-right-up-down-to-fro movement. Resonance in a molecule will result in heat- that's how microwave ovens work. Resonance in a liquid will result in waves. Kids often discover this in the bath, when they make splashes at just the right frequency to amplify them over the side of the tub. Resonance in a sugar pill will cause it to crumble.

A quick googling will reveal arnica montana, bee venom, belladonna, arsenic etc. to be actual substances - and yet when prepared homeopathically, like calendula, they should be ineffective according to your argument.

All I'm saying is that in my experience, the shit works. If you're saying that you're not buying it because current science can't explain it to your satisfaction - I'm fine with that. And it still works.

I did not know that Bob Dole was a side effect...

Yes, when prepared homeopathically, they are useless. Calendula as well. If they are prepared in an herbal or folk concoction, they may be useful (or harmful). That's one thing that is good about homeopathic remedies- they can honestly say there are no harmful side effects, as there are no effects at all.

For example, if you take some calendula and mix it with fat, and smear it on a burn, then you are applying calendula to the burn. If calendula is efficacious, then it will have its effect.

If you take calendula, and mix it into ten units of water, and then repeat that process thirty times, then all you will have left is water, and when you put it on a burn, it will be as useful as water.

So calendula 1X HPUS in fat would do what?

Apparently 1X means one part calendula to 9 parts water. So there's still some actual ingredient in there. It would do whatever calendula does. If smearing calendula on a burn is helpful, is still may work in a 1X.

On the other hand, getting a 90% water mixture to stick in fat is a bit of a trick. You'd be better off using the raw calendula and putting the right dose directly into the fat. 0X HPUS, if you will.

Assuming, of course, that calendula is beneficial in the first place.
