Summary
Ginseng overdose can cause serious eye problems like blurred vision and pupil dilation. These symptoms, along with dizziness, may result from overstimulation of the sympathetic nervous system.
Area of Science:
- Pharmacology
- Toxicology
- Ophthalmology
Background:
- Ginseng is widely recognized for its tonic properties, impacting both cognitive and physical functions.
- Extensive pharmacological research has documented a diverse range of ginseng's effects.
Observation:
- This report details two cases of ginseng poisoning.
- Patients exhibited bilateral mydriasis (pupil dilation) and impaired accommodation (difficulty focusing).
- Systemic symptoms included dizziness and a state of semiconsciousness.
Findings:
- The observed ocular and systemic effects suggest a potential link to the hyperexcitability of sympathetic nerves (adrenergic nerves).
- This hyperexcitability is hypothesized to be a direct consequence of ginseng overdose.
Implications:
- These findings highlight the potential toxicity of ginseng when taken in excessive doses.
- Understanding these adverse effects is crucial for clinical diagnosis and management of ginseng-related poisoning.
- Further research into the precise mechanisms of ginseng's sympathomimetic effects is warranted.
