Consumption of tansy, especially in large amounts or over a long period, can lead to significant toxic effects due to chemicals found within the plant.
Understanding Tansy's Toxicity
Tansy contains a chemical called thujone in its volatile oil, which is primarily responsible for its adverse effects. Even skin contact can cause irritation. Internal consumption, particularly if prolonged or in excessive quantities, can lead to severe health issues.
Specific Side Effects of Tansy
The side effects of tansy consumption range from mild to life-threatening, affecting multiple body systems. It's crucial to understand these risks before any exposure or ingestion.
Here are the potential side effects:
| System Affected | Side Effects | Description |
|---|---|---|
| Neurological | Neurointoxication, Convulsions | Can affect the brain and nervous system, leading to altered mental states and uncontrolled muscle contractions. |
| Cardiovascular | Cardiac Depression | Weakening of heart function, potentially leading to reduced blood circulation. |
| Respiratory | Respiratory Depression | Slowed or shallow breathing, which can reduce oxygen intake and be life-threatening. |
| Gastrointestinal | Gastritis | Inflammation of the stomach lining, causing pain, nausea, or vomiting. |
| Dermatological | Skin Irritation | Redness, itching, or rash upon direct contact with the plant's volatile oil. |
| Severe Outcomes | Death | In severe cases of overdose or prolonged exposure, consumption can be fatal. |
Key Considerations
- Dosage and Duration: The severity of side effects often correlates with the amount of tansy consumed and the duration of exposure. Long-term use or large single doses are particularly dangerous.
- Thujone Content: The concentration of thujone can vary, but its presence makes tansy inherently risky for internal use.
- Vulnerable Populations: Individuals with pre-existing heart, respiratory, or neurological conditions may be more susceptible to severe reactions.
Given the range of serious side effects, tansy is generally not recommended for internal consumption.
