Endogenous (specific) and exogenous (non-specific) factors for the cause of asthma are given. The endogenous factors are referred to the Organon Para 78 on chronic disease. The exogenous factors are referred to the Organon Paras 81, 74 and 77, on allergies and environmental causes. In latent psora the person appears to be in good health. The first manifestations of psora in the newborn are eczema, allergic erythema etc. and later urticaria, neurodermatitis etc. The next stage is the change from cutaneous to respiratory allergies such as asthma. This is illustrated by a case report. A 48-year old patient had asthma, nasal polyps and allergy to aspirin, housedust and pollen. She was prescribed Actea racemosa, Salicylic acidum (because of the aspirin allergy), Sambuccus and Arsenicum album. A year later the patient no longer had asthma attacks, and she was still taking only Salicylic acidum and far less inhaled corticosteroid than previously.
