Usage
Ginseng extract is primarily used for its adaptogenic properties, helping the body cope with stress. It’s also used to potentially enhance cognitive function, boost the immune system, improve physical performance, and regulate blood sugar levels. It is classified as an adaptogen and is also considered to have immunomodulatory properties. The mechanism of action is complex and not fully understood but involves multiple interactions with the body’s systems, affecting hormone levels, the immune system, and nerve function.
Alternate Names
Ginseng extract is also known as Panax ginseng (Asian ginseng) or Panax quinquefolius (American ginseng). Brand names include Cold-fX.
How It Works
Pharmacodynamics: Ginseng affects multiple systems. It influences the hypothalamic-pituitary-adrenal (HPA) axis, potentially reducing the effects of stress. It also has potential impacts on blood sugar regulation by influencing insulin secretion and sensitivity.
Pharmacokinetics: Ginseng components (ginsenosides) are absorbed through the gastrointestinal tract. They are metabolized, primarily in the liver, by CYP enzymes. Elimination pathways are not fully characterized, but involve both renal and hepatic excretion.
Mode of Action: Ginseng’s mechanism is multifaceted. It is thought to influence neurotransmitter systems, impacting neuronal excitability. It also has antioxidant effects and affects the immune system. More research is needed to completely define its interactions at the cellular and molecular level.
Dosage
Standard Dosage
Adults:
Dried root: 0.5 to 3 grams daily for up to 3 months. Extract: 100 to 800 mg daily. It is essential to consult with a healthcare provider to determine the appropriate dosage and duration of use for each individual.
Children:
Ginseng is not recommended for use in children due to limited safety data.
Special Cases:
- Elderly Patients: Close monitoring is recommended due to potential interactions with other medications.
- Patients with Renal Impairment: Caution is advised. Dosage adjustments may be necessary.
- Patients with Hepatic Dysfunction: Caution is advised as ginseng is metabolized in the liver.
- Patients with Comorbid Conditions (Diabetes, Cardiovascular disease, etc.): Close monitoring of blood glucose and blood pressure.
Clinical Use Cases
Ginseng extract’s use in specific clinical settings, such as intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations, is not well-established, and there are no standard dosage recommendations for these situations.
Dosage Adjustments
Dose adjustments are crucial for patients with renal or hepatic impairment. The appropriate adjustments depend on the degree of dysfunction and require careful consideration and close monitoring.
Side Effects
Common Side Effects
Insomnia, headache, nervousness.
Rare but Serious Side Effects
Allergic reactions (including anaphylaxis), liver damage, mania.
Long-Term Effects
Long-term effects are not well-studied. Some data suggest potential hormonal effects with prolonged use.
Adverse Drug Reactions (ADR)
Severe allergic reactions.
Contraindications
Hypersensitivity to ginseng, pregnancy, breastfeeding. Use with caution in patients with schizophrenia or scheduled for surgery.
Drug Interactions
Ginseng can interact with several medications, including warfarin, phenelzine, oral hypoglycemics, insulin, and caffeine. It can also interact with other herbs with anticoagulant/antiplatelet properties. It is important to review patient medication lists for potential interactions.
Pregnancy and Breastfeeding
Ginseng is contraindicated during pregnancy and breastfeeding due to potential risks to the fetus and neonate.
