Dear Anna
Before coming to details related to the topic I would like to put a few lines
About Psorinum . Psorinum prepared from nosode but Hahnemann forbids to prescribe
as ITCH disease directly .Unless well indicated by drug picture like other medicines Psorinum will fail to bring the cure
concept of nosodes ( views and work presented by Dr. Paterson Homeopathic hospital Glassow in 1949 )
A NOSODE IS LIKE A VACCINEIN SOME RESPECTS BEING DERIVED FROM THE CULTURE OF A PARTICULAR ORGANISM, BUT CONTAINING NO ACTUAL GERMS OR BACTERIA.
It is used to stimulate the body to produce natural antibodies against the infection..
Thus in Homeopathy ther are nosodes for use in chicken pox, whooping cough,and measles to take three well known examples.so that the homeopathic nosodes prepared from culture of forgoing organisms and which in words of Dr.Paterson are in the nature
Of a kind of potentised vaccine having the power to restore a disturbed metabolism to health
All the nosodes have been proved homeopathically on healthy volunteers by assessing their action
In the words of Dr. paterson
1. specific organism is related to disease
2. …………………………….to remedy
3. the remedy is related to the disease

Hahnemann’s saying of psorinum and psora is not to give psorinum for itch disease
Unless called by totality
(it is what I learnt ) …….to be continued
(details of Dr.Paterson works)
(more views on the subject )
sorry , my typing is slow
