Average fatal dose of croton oil seed is –
**Core Concept**
Croton oil is a highly toxic and irritant substance derived from the seeds of the Croton tiglium plant. It contains a mixture of diterpenoid esters, including crotonoside, which is responsible for its toxic effects. The average fatal dose of croton oil seed is a critical piece of information in poison management and toxicology.
**Why the Correct Answer is Right**
The toxic effects of croton oil seed are primarily due to the action of crotonoside on the gastrointestinal tract, causing intense irritation and inflammation. The exact mechanism of action involves the release of histamine and other mediators, leading to vasodilation, increased permeability, and fluid accumulation in the affected area. The high potency of croton oil seed makes it a significant threat to human health, and estimating the average fatal dose is essential for prompt medical intervention.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely too low, as the actual fatal dose of croton oil seed is significantly higher.
**Option B:** This option is too high, and the actual fatal dose is lower than the reported value.
**Option C:** This option is not supported by scientific evidence, and the exact fatal dose of croton oil seed is typically reported in a different range.
**Clinical Pearl / High-Yield Fact**
The croton oil seed is highly toxic and can cause severe gastrointestinal irritation, leading to symptoms such as vomiting, diarrhea, and abdominal pain. In severe cases, it can lead to respiratory failure, cardiac arrest, and even death.
**Correct Answer: C. 1-2 grams
