Properties of the soil, state of the particules, class of the soil and air, water and the chemicals (calcium cations, humus, colloidal iron, aluminum, nitrogen, various polysaccharides etc.) that soil contains are the most important factors on formation and development of the plants. Trace elements play an important role in the active chemical formation in medicinal plants and are responsible for the toxicity of medicinal plants.
