you haven't lost that magic - you know why placebo really works? it's the context, the ritual of going to a "making you healthy" building, talking with a "i'll make you healthy" person, and then receiving a "healthy making" pill. the ritual is what makes the magic of placebo happen, it's what makes the belief that it'll work easier.

what home remedies/traditional cures have lost is the ritual of watching your grandmother, or in the older times the local wise woman, preparing your "cure". A wise person giving you a drink or something and promising that'll make you feel better is on the same level as a doctor giving you a pill.

just buying over the counter meds without a doctor's order, or just making your own health brew isn't as effective

also don't forget that placebo work even when you know it's placebo, that's how powerful the ritual of it is. i don't know if it's some low magic, or if our subconscious has a deeper control over our body than we realise, but the fact is - it works on everyone

You just need somebody to put a coat on and say it's OK

I'm luckily immune to learning about the placebo effect. The essential oils make my home a garden for one of the five senses, guarded by an army of leeches and caged in quartz. My meridians are supersymmetric across six zodiacs and are sensitive enough that you can use my body to measure the effects of climate change on leylines.
