Origin & tradition

Ci Wujia (刺五加, Eleutherococcus senticosus) strengthens the kidneys and spleen and builds stamina. Used in Chinese medicine for centuries before becoming prominent in Soviet sports and cosmonaut programs.

Why longevity buyers care

Key active: Eleutherosides B & E (root bark of Eleutherococcus senticosus).

Eleutherosides B and E modulate the HPA axis and NK/T-cell immune function. Soviet-era studies documented endurance, cognitive, and immune benefits in athletes and military personnel. Modern human trials focus on immune function, fatigue, and exercise performance; mechanistic aging data (oxidative stress, mitochondria) is preclinical.

Human trials on stress/immune/endurance; aging-specific studies preclinical

Eleutherosides B and E modulate the HPA axis and NK/T-cell immune function. Soviet-era studies documented endurance, cognitive, and immune benefits in athletes and military personnel. Modern human trials focus on immune function, fatigue, and exercise performance; mechanistic aging data (oxidative stress, mitochondria) is preclinical.

    Key active: Eleutherosides B & E (root bark of Eleutherococcus senticosus) — a multi-compound botanical extract, so activity is not reducible to a single molecule.
