It is not good to reduce medication quickly, and it must be reduced evenly, something that most people do not understand. Most people think that drugs play a therapeutic role, while in fact the role of drugs is in a sense substitution, a replacement of certain functions of the organism. Mental illness is biologically like a lack of a certain substance, and drugs are replacing that gap. When the gap is large, the impact of more links and transmitter systems, in dysfunction, loss of compensation, the body can not be repaired; only when the gap is reduced to a certain extent, it can be resolved by the natural repair ability; after repair, it can be in the gap is widened to the range of natural repair, that is, drug reduction. The natural healing process of the human body is slow and varies from person to person. The ability to repair decreases with age; chronic illness or recurrent attacks can transform some reversible functional damage into irreversible damage with organic factors, resulting in incomplete recovery. The ability to repair is also related to a person’s physical and psychological state. Therefore, some people are able to lose and some cannot finish. Only when the treatment is effective, that is, when the drug makes the body’s functional body basically reach normal, will the body exert its own instinct of repair (the disease has stimulated the body’s recovery, but the speed is not yet faster than the speed of the balance being destroyed, so it is a kind of vicious circle; when the drug stops/slows down further destruction, then the speed of recovery is greater than the speed of destruction, and only then can it enter a virtuous circle), so that the person can truly sense But when the body recovers to a certain extent and the drug is reduced to a certain extent, due to the cause of the body’s own disease (not known, because the treatment of mental illness is not allopathic), a new balance is reached (the body’s recovery rate has slowed down or even stopped, and the disease factor is not strong, but the two regained balance), it can not continue to reduce , further reduction will again create an imbalance, creating a vicious circle and a worsening/relapse of the disease. The same factor may be detrimental if the body has this ability to recover without timely drug reduction. In chronic patients, this healing ability has diminished or disappeared, so it is not possible to stop the medication, but only to take it for a long time. Because the body’s self-repair is not accomplished overnight, but gradually, there should not be large fluctuations in drug concentrations. This is why the current trend of drug development is not to produce new drugs, but the development of slow-release dosage forms, in order to just maintain a smooth blood concentration. The benefits of long-acting injections include this, and that is why they are more effective than oral tablets in negative symptoms, etc. The main role of herbal medicine is to promote this healing ability, so most of the role of herbal medicine is icing on the cake, not snowing on the cake.
