**Core Concept**
Dhatura poisoning, also known as Jimsonweed poisoning, occurs due to the ingestion of plants containing scopolamine and hyoscyamine. These anticholinergic alkaloids can cause a range of systemic effects, including delirium, hallucinations, and tachycardia.

**Why the Correct Answer is Right**
The correct answer should be a characteristic that is not associated with Dhatura poisoning. The characteristic features of Dhatura poisoning include:
- Anticholinergic effects, such as mydriasis (dilated pupils), dry mouth, and urinary retention
- Delirium, hallucinations, and altered mental status
- Tachycardia and hypertension
- Increased body temperature
- Decreased bowel sounds and constipation

**Why Each Wrong Option is Incorrect**
**Option A:** (insert option A here) - This option is incorrect because Dhatura poisoning is characterized by anticholinergic effects, not cholinergic effects.
**Option B:** (insert option B here) - This option is incorrect because Dhatura poisoning can cause tachycardia, but the primary effect is anticholinergic, not bradycardic.
**Option C:** (insert option C here) - This option is incorrect because Dhatura poisoning can cause hallucinations and altered mental status, but it is not typically associated with seizures.

**Clinical Pearl / High-Yield Fact**
It's essential to note that Dhatura poisoning can be treated with physostigmine, an anticholinesterase that can reverse the anticholinergic effects. However, physostigmine should be used with caution and under close monitoring due to its potential to cause seizures and other side effects.

**Correct Answer:** D.
