The “Spirit” section for psoriasis comprises energetically oriented treatments that have to do with intention, energy healing, prayer, and in some cases god.
Physical activity is important for the treatment of all health conditions, including psoriasis. On a purely physical level, exercise can increase circulation and help the body rid itself of the toxins it carries within, and often times these toxins manifest as dry skin. In addition to helping the body function more properly on a physiological level, the meditative component inherent in a yoga practice can help with physical illness' manifestations as well.
Since an underlying bodily imbalance or blockage is what brings the problem of psoriasis to the surface, acupuncture works to remove this blockage from the inside out. So depending on the individual's specific imbalance, acupuncture would work to specifically remove that person's blockage, resulting in a reduction or elimination of the visible symptom of psoriasis.
