Lymph nodes are prioritized in protecting and ensuring endoecological safety at different periods of life, especially in retirement age. It destabilizes the structure and function of the lymphatic system and organs when aging increases the risk of comorbid conditions. This is a sign of age-related pathology. Improving lymph node function is an essential task in integrating gerontology and lymphology. The solution to this problem is possible with the help of a phytotherapeutic agent, which involves the evaluation of efficacy with effect on intranodular functional systems - compartments, hydration, and trace elements. Phytotherapy weakens (slows) the intensity of the old lymph node changes. Phytotherapy has a modifying effect on structures with increased hydration and trace element concentration. Phytotherapy prevents age-dependent changes in the lymph node and increases the reliability of lymph node operation in old age.
