• Isabgol (Psyllium husk, obtained from the seeds of Plantago ovata) is rich in water-soluble dietary fiber and mucilage (xylan and arabinoxylan polymers).
• Upon ingestion, the husk swells up to 10 to 14 times its original volume by absorbing water in the gastrointestinal tract, forming a soft, lubricating gelatinous mass that increases stool bulk and promotes peristalsis to relieve Constipation.
• It is widely prescribed as a natural, non-habit-forming bulk laxative.
• Hence, Isabgol is primarily recommended for Constipation (Option 2).

Analysis of isabgol seed rate:

• 6-8 kg/ha: Isabgol (Plantago ovata) seeds are tiny with test weight of 1.5–2.0 g; the recommended seed rate is 4 to 8 kg/ha (commonly 6-8 kg/ha) for line sowing.
• 10-12 kg/ha: High seed rate that leads to over-crowding and downy mildew.
• 13-15 kg/ha: Far above standard requirements.
• 18-20 kg/ha: Excessively high for small-seeded medicinal crops.
