Securinega is common in Eastern Siberia (Nerchinsk Dauria) and in the Russian Far East.

Medicinal raw materials are leaves, stems no thicker than 3 mm.

The active principle is the alkaloid sekurenen, the content of which reaches 0.3%. Preparations containing securine have a stimulating effect on the central nervous system, especially increase the excitability of the spinal cord (securine is similar in nature to strychnine, but is 8-10 times less toxic and inferior to it in terms of strength of action).

It is used in the form of securenin nitrate in asthenic conditions, neurasthenia, fatigue, paresis and flaccid paralysis (during the recovery period after poliomyelitis), with sexual weakness due to functional nervous disorders.
