Therapeutic Indications

Marīca is one of the primary Dīpana-Pācana dravyas mentioned in Charaka Samhita and Bhavaprakasha Nighantu.
It corrects Agni, clears Ama, and acts as a natural bio-enhancer (Yogavāhi) — potentiating the effect of other herbs.

Indicated in:

• Agnimandya (Weak digestion, low metabolism)

• Āma-janya Vikāras (Toxin accumulation disorders)

• Kāsa (Cough), Śvāsa (Asthma, breathlessness)

• Pratiśyaya (Cold and sinus congestion)

• Krimi (Intestinal worms)

• Śotha (Inflammation, swelling due to Ama)

• Ārochaka (Loss of appetite)

• Kapha Medo Roga (Obesity, sluggish metabolism)

Pharmacological Insights

Marīca contains piperine, an alkaloid responsible for its pungency and pharmacological potency.
It enhances gastrointestinal enzyme secretion, improves bioavailability of nutrients and drugs, and exhibits antimicrobial and anti-inflammatory effects.
These properties correlate with its Ayurvedic roles as Dīpana, Pācana, and Yogavāhi.
