It is clear that homoeopathy does not work, as a review of 225 studies confirmed: NHMRC statement and advice on homoeopathy

I used to think that homoeopathy is mostly harmless and is only a waste of money. I changed my mind, based on what 80000hours.org has to say:

There are a lot of useless products that don’t work. Sometimes the people selling them know they are useless. Mostly they just end up wasting people’s time and money, which wouldn’t be enough to earn them a place on this list.

What sets fraudulent medical technologies like homoeopathy apart is that they often discourage misinformed people from using established medicines that would actually cure their conditions. Homeopathic medicines masquerade as real medicines in pharmacies, for those who aren’t aware that homoeopathic medicines have no impact at all.
