Rhodiola rosea is a flowering plant that has been shown to reduce the stress response and reduce anxiety and fatigue (Olsson 2009; Panossian 2007; Ishaque 2012). In particular, supplementation of rhodiola helps patients with severe anxiety. The usual dosage is 100–200 mg daily. Ashwagandha (Withania somnifera) is an herb from the Indian Ayurvedic healing tradition that ameliorates the effects of stress in rats and humans (Bhattacharya 2003; Chandrasekhar 2012). The usual dosage is 150–300 mg daily.
