Step 1: Understanding the Concept:
Many non-timber forest products (NTFPs) include seeds and fruits of wild forest plants that contain potent secondary metabolites with highly specific therapeutic values.
Step 2: Detailed Explanation:
Psoriasis is a chronic, non-contagious skin disorder characterized by rapid, abnormal multiplication of skin cells, leading to dry, red, itchy patches.
The seeds of Psoralea corylifolia (commonly known as Babchi or Bakuchi) contain a high concentration of active furanocoumarins, particularly a compound called psoralen.
In modern and traditional medicine, psoralen acts as a potent photosensitizing agent.
When the seeds are processed into oil or extracts, applied to the skin, and exposed to controlled ultraviolet light (PUVA therapy), psoralen binds to cellular DNA. This action slows down the hyper-proliferation of skin cells, effectively managing psoriasis and vitiligo.
Let us review the other options:
- Cineraria maritima is primarily used to formulate homeopathic eye drops for cataracts.
- Glycyrrhiza glabra (Mulethi) is used for treating throat, respiratory, and digestive issues.
- Evolvulus alsinoides (Shankhpushpi) is a well-known Ayurvedic brain and memory tonic.
Step 3: Final Answer:
Therefore, the seeds of Psoralea corylifolia are utilized in the treatment of psoriasis. This corresponds to option (B).
