I can't access the archives on that site, which is why I couldn't find the relevant info.

I found that I was looking at two remedies whose only similarity seems to be that they are ranunculacae. I want to discover what are the unifying qualities of the ranunculacae remedies.

Don't think it's Cannabis thanks. There's no aetiology for it and all the fears in the case are related to one central fear. Drowning, flying etc are all secondary and consequential.
