I am not certain about the exact procedures, but it is taken a biopsy, succulated (?)= diluted, shaken over and over again until it is only the energy / spirit left, then transferred to lactose. http://www.tinussmits.com/3861/carcinosinum.aspx
Until recently I thought that the Carcinosinum we use all over the world, was everywhere the same. The one I used all the time was from Dolisos in Holland, which is the same as that from Nelson in London and is made at least with 15 different tumors. Colleagues who attended my seminars in the past and tried to apply my way of treatment told me that they were not able to obtain the same cures with Carcinosinum as I did and that they didn’t see as often as I did the shift to the next layer (most of the time that of Saccharum officinale) after a prolonged treatment with this remedy. One colleague from the USA even wrote to me: ‘Maybe you have special ability to connect and transmit healing through your understanding, because our results with Carcinosinum are not as good as yours.’ Though his explanation was very flattering for my ego, I was seeking for another explanation that I found only two years later: the quality of their Carcinosinum was not the same as the one I used. The one-tumor-Carcinosinum, made with a mammary tumor of one woman is surely not universal enough to resolve the whole Carcinosinum layer and not capable of causing a shift to the next layer. In many cases the one-tumor Carcinosinum will give only partial results for a short time and that’s what happened to my colleagues in the USA when they tried out what I taught them.
The Nelson Carcinosinum (London) is made of the following different carcinomas: Carcinoma Adeno (stomach), Carcinoma Papillary (colon), Carcinoma Papillary (ovary), Carcinoma Papillary (uterus), Carcinoma (bowel), Carcinoma Co. (bowel), Carcinoma Co. (K) -(K is a composite of carcinomas supplied by Koch Light)- Carcinoma Scirrhus (mamma), Carcinoma Scirrhus (stomach), Carcinoma Squamous (pulm). (source: A. Nelson & Co Ltd, London).
A little investigation in different countries taught me that there are Carcinosinums made out of 58 different tumors (source Stauffen, Germany) and of only one tumor. This gives us the following listing:
Holland: Dolisos 15
Belgium: Homeoden 1
Germany: Stauffen 58, with exclusion of bowel tumors
France: Dolisos Prohibited!
Switzerland: Dolisos 15
USA: Boiron 1
