Yep Nigel, some RSHOM's don't know what they are doing.
But, I must put a word of caution in, with regards to Radionics (which is basically the same as Hulda Clarkes methods, btw!!) - and this came from my own homeopath - after asking her about it (and giving her one of my books by Dr Clarke to read out of interest for discussion)....
She said she has been following 3 cases for something like over 25/30 years - people who used Radionics (and sometimes Homeopathy). Two of the three have died (one less than two years ago) - both with growths/tumours on their brains. The third has growths on the brain. She strongly advises against the use of radionics. She suspects it has side effects - none of which anyone can be certain of - because it hasn't been properly researched, etc. I defer to her on this, because I haven't studied long enough and don't have the clinical experience she has.
I recently had a neck problem (a couple of months back) - incidentally...and I was in so much pain - that whilst waiting for my remedy to arrive (by post), I used a TENS Unit on my neck (to loosen the muscles) - hadn't even thought to ask her if this was an okay modality! (in hindsight, it's the same principle - or near enough - as Radionics, I suppose).
In the meantime, while I had the right rem - I had it in the in wrong potency - so, I had been plussing it in water to gain a bit of relief at the same time (and it did afford short periods of relief). I ended up with a horrid headache after using the TENS.
I rang to ask if I could take another dose (whilst still waiting for the right potency to arrive) because I had tried the TENS and not only was it no longer giving a lot of relief - but I now had a horrible headache.
She reminded me of our conversation about Radionics, etc..and said that if I needed some relief - better to use some tiger balm or something similar. TENS was okay but not on parts of the body near the head (i.e. brain). She suspected that is what caused the headache. Funnily enough, I took nothing ----- only used some tiger balm on upper back/neck area and within a couple of hours, the headache was gone. (for the headache, I just laid down and rested and it went...took nothing for it...and I have to stress - it was nasty

).
Just some food for thought, I thought I'd share.
