I am aware. Didn’t mean it that way.
Say an owner gets worked up and stresses about fireworks messing with their animals, fusses all around them, tries to “calm” them by moving them or giving extra attention and in turn stresses the animal out by them feeding off the anxious energy.
Then owner applies homeopathic concoction of essential oils and sits back, waiting for it to kick in. Suddenly the owner is calm and not fussing with them and in turn the animal starts to wind down. Owner sees them winding down, relaxes, situation diffuses.
If it works then it works, placebo or not. I’m not bashing it, but the above example and similar situations are extremely common testimonials and hold no weight for me personally.
