Ashwagandha (Withania somnifera) vs Siberian Ginseng (Eleutherococcus senticosus)

Ashwagandha (Withania somnifera)

Siberian Ginseng (Eleutherococcus senticosus)

About

Ashwagandha (Withania somnifera), sometimes called “Indian ginseng,” is a sturdy shrub growing to about 5 ft (1.5 m) with oval leaves, greenish or yellow flowers, and small, round fruits. NCCIH says some preparations may help insomnia and stress, but there isn't enough evidence to know whether it helps most other conditions.

Siberian ginseng (Eleutherococcus senticosus), also called Eleuthero, is a deciduous, hardy shrub reaching up to about 10 ft (3 m). It features 3-7 toothed leaflets per stem and spiny branches. Regarded as an adaptogen, Siberian ginseng has been used traditionally as an adaptogen, performance enhancer and immunostimulant; MSK says studies in humans are quite limited.
