Question

Amongst the followings, which one is better known for therapeutic value against asthma ?

• A. Ricinus
• B. Nerium
• C. Tylophora
• D. Datura

Hint:

Its species name literally references the disease it is traditionally used to treat.

Answer 1

The Correct Option is C

Step 1: Among the given plants, Tylophora indica (also called Tylophora asthmatica) is specifically cultivated and studied for its use against bronchial asthma.

Step 2: Its leaves contain the alkaloid tylophorine, which has documented anti-allergic and bronchodilator properties and has been used in traditional Ayurvedic and folk medicine to relieve asthma attacks.

Step 3: Ricinus (castor) is valued for its seed oil, Nerium (oleander) is a cardiac-glycoside-containing ornamental known for its toxicity, and while Datura has historically been smoked to relieve asthma symptoms, it is far better known for its toxic tropane alkaloids and psychoactive/poisonous effects than as a therapeutic asthma remedy.

Step 4: So the plant better known specifically for anti-asthmatic therapeutic value is Tylophora.
