Panex ginseng is known as the King of Herbs and was used in Asia to absorb energy from the earth, prolong life, tonify the five viscera, benefit the understanding and replace lost Qi. It was also considered an aid in study and spiritual development.
- Cognitive Support
- Can help improve memory, focus and concentration.
- Stress and fatigue (physical and mental), chronic fatigue, low vitality, weak and elderly people, to improve learning, convalescence
- Immune Support
- immune compromise and stress, cancer (especially during radiation)
- increases endurance and performance by sparing muscle glycogen stores during prolonged exercise
- Other Conditions
The information provided is intended to augment the treatment from a naturopathic doctor or other trained medical professional. Although most herbs are generally safe, it is recommended that you avoid self-prescribing especially when there is an underlying ongoing medical condition, if you are on any prescription medications or if you are pregnant or breastfeeding.

- Drug-Herb Interactions.
- Amoxicillin and Related Beta-Lactam Antibiotics - Beneficial or supportive interaction not requiring professional management; Ginseng increases T helper cell type 1 (Th1) immunity and may enhance effectiveness of many antimicrobial agents, although evidence of interaction is specific to amoxicillin (clinical significance: possibly widely applicable but not currently known). Consider co-administration especially in antibiotic-resistance and in immunocompromised.
- Antineoplastic Chemotherapy and Radiotherapy - Potential or theoretical beneficial or supportive interaction with professional management, prevention or reduction of drug adverse effect; Ginseng may decrease drug toxicities and increase drug efficacy through multiple mechanisms, including immunomodulation, chemosensitization, and specific toxicity reduction (Western clinical support negligible, despite anecdotal clinical support). Pretreatment and co-adminstration with chemotherapy and radiation recommended with professional management.
- Ethanol - Impaired drug absorption and bioavailability with negligible effect, prevention or reduction of drug adverse effect, beneficial or supportive interaction not requiring professional management; Clearance of alcohol may be increased by Ginseng pretreatment.
- Narcotic Analgesic (Opiates) and Psychostimulants - Interaction likely but uncertain occurrence and unclear implications; Ginseng may reduce drug-induced tolerance development and decrease adverse effects of drug use. Consider possible use as additional support for adverse effect reduction in analgesia or withdrawal from narcotic/opioid abuse.
- Phenelzine and Other Monoamine Oxidase (MAO-A) Inhibitors - Potential or theoretical adverse interaction of uncertain severity; Ginseng effect on neurotransmitters not considered physiologically significant. Current low use of nonselective MAOIs renders clinical significance marginal (interaction overstated).
- Vaccine Immunotherapies - Potential or theoretical beneficial or supportive interaction with professional management; Ginseng extracts may increase antibody response and effectiveness of some vaccine therapies by enhancing antigen-presenting cell (APC) activity. In particular, ginsenosides may be a useful pretreatment and adjuvant for improving potency and immunogenicity of vaccines.
- Warfarin and Related Oral Vitamin K Antagonist Anticoagulants - Potential or theoretical adverse interaction of uncertain severity; INR reduction in a single report, probably idiosyncratic (significance unknown, likely minimal). Observe normal INR monitoring, especially if adding or removing any drug/herb to stable anticoagulation.
