That is incorrect. If you read what Cayce had to say about Psoriasis, he was clearly focussed on the introduction of toxins through the digestive tract related to inadquate function of the lymphatics. The lymphatic system is not synonymous with the immune system. Rather part of the lymphatic system contains part of the immune system. But another funtion of the lymphatic system is the absorption of fats from the digestive tract which are passed through the thoracic duct into the general circulation. His continued focus on the intestine means that he was specifically not referring to the immune system when he was referring to lymph circulation. The lymphatic system has several functions, only one of which involves the immune system, and none of what he said could be taken as corresponding to that component of the lymphatic system.
When did physicians first start using the term "immune system"?
From the text I referenced earlier (The Home Physician):
"Associated with psoriasis, and possibly a causative factor, are rheumatic and gouty conditions, as well as digestive disturbances."
"Local treatment seems not to produce any permanent effect, unless the habits of the patient are materially changed." - followed by a list of dietary changes plus a recognition that systemic conditions (such as gout or rheumatic conditions) must be treated to effect a recovery from psoriasis.
"The condition is believed to be due to the action of a toxin produced...in another part of the body."
I have to admit that sounds somewhat like Cayce. Still, it's quite a bit different than Cayce's Reading 289-1, given March 2, 1933:
"Q. Please give me the cause and cure for the so-called psoriasis with which I am troubled.
"A. The cause is the thinning of the walls of the intestinal system, which allows the escaping of poisons - or the absorption of same by the muco-membranes which surround same, and becomes effective in the irritation through the lymph and emunctory reactions in the body.
"An effective cure for same is first being mindful of the diet, during the periods when these necessary elements would be given for creating those activities within the system to close such conditions:
"In the system we would use elm water and saffron water. These would be taken in the ordinary drinking water, during periods of one, two to three weeks at a time. All the drinking water, carrying, then, either a small quantity of elm or the Saffron. For this adds to the assimilating system those properties that become effective to the aiding of building within the system itself those conditions that will overcome such activities in the system.
"The diet during such periods should be more of vegetables than of meats or sweets, so that there are those reactions that make for better unification in the membranes' reaction within the body."
From the 1910 EB:
"The treatment is hygienic, constitutional and local. "
"The internal administration of small doses of vinum antimoniale, in acute cases, or of arsenic (in gradually increasing doses of the liquor arsenicalis) in chronic cases, is undoubtedly beneficial."
Cayce never recommended vinum antimoniale or arsenic as a treatment for psoriasis.
Clearly it was already recognized as the skin manifestation of a systemic disease, that the digestive system was somehow involved, and that while local treatments could help, systemic treatments may provide a more complete effect.

Okay, perhaps there was more understanding than I thought there was in Cayce's era that psoriasis involved more than a skin problem, but still, it seems that Cayce was recommending a fundamentally new approach. For example, where do you suppose he came up with the idea of "thinning of the walls of the intestinal system"?
