गेंड्याच्या शिंगाचा प्रमुख औषधीयुक्त उपयोग काय समजला जातो ?

The correct answer is Option B (Aphrodisiac).

Key Points:
• Wildlife Poaching & Rhino Horn Myths:
• Composition: Rhinoceros horns are composed entirely of compacted keratin (the same structural protein found in human hair and fingernails) and possess no scientifically proven pharmacological value.
• Traditional Myths: In Traditional Chinese Medicine (TCM) and Asian folk medicine folklore, powdered rhino horn has been historically traded illicitly as an alleged aphrodisiac (enhancing sexual potency) and as a treatment for fever and convulsions.
• Conservation Threat: This widespread myth fuels illegal poaching of the endangered Indian One-horned Rhinoceros (*Rhinoceros unicornis*) in protected areas like Kaziranga National Park.
• Hence, the traditional alleged medicinal myth associated with rhino horn is as an aphrodisiac.
• Key Takeaway: Rhino horn (made of keratin) is illicitly poached due to the unfounded traditional myth of being an aphrodisiac.
