Immune system, together with central nervous system and hormonal system, is one ot the three basic systems that regulate human organism, responding to current needs, and both internal and external stimuli.

Immunological, competent cells, such as macrophages, dendritic cells T-and B- Iymphocytes, and granulocytes play an important role in the immune system. Cytokines are the main information carriers from one celi to another. Immunoreactive level depends on the correct cooperation ot these systems - whether a given particie is recognised as own or foreign also depends on the antigen formation in HLA [human leukocyte antigen]. Only cooperation ot all these elements decides on an organism immunoreactive level - whether it is going to fight or tolerate a given element.

The results ot studies published in the best Polish journals clearly indicate that TPP (TOŁPA Peat Preparation) belongs to immunomodulators - i.e. the substances, whichstimulatethe immunesystem when appliedin low doses and are immunosuppressive in high doses. Interestingly, it has been demonstrated that in order to obtain the optimum effect ot TPP, the so-called pulsation method ot application and not the continuous method should be used. It should be emphasised that the preparation causes no side effects when applied in therapeutic concentrations - i.e. it is safe in use.

The demonstrated multidirectional action ot the preparation becomes comprehenslble when taking into consideration the new information related to functloning ot immune system. This is the system that pertains to the whole organism whose main activity involves continuous supervision ot antigen stability ot the organism and elimination ot any occurring disorders.

Application ot the preparation to supplement diet will positively influence formation ot human immunity. It should again be emphasised that relatively tew preparations, partlcularly those ot Polish origin, can be accompanied 'with such rich and versatile scientific literature speaking in favour of TPP application.
