dīpanojvaratṛṣṇāghnastiktaḥ śodhanaśoṣaṇaḥ / pittalo lekhana stambhī kaṣāyo grāhiśoṣaṇaḥ
รสขมเป็นทีปนะ ช่วยดับไข้และกระหาย อีกทั้งชำระและทำให้แห้ง; รสฝาดทำให้ปิตตะกำเริบ มีฤทธิ์ขูดกวาด (เลคหนะ) ทำให้หดรัด เป็นกราหีคือช่วยยึดกุม และทำให้แห้ง
Lord Vishnu (in instruction to Garuda/Vinata-putra)
Dosha: Vata/Pitta/Kapha
Concept: Functional pharmacology of tastes: tikta is dīpana and jvara-tṛṣṇā-hara, śodhana-śoṣaṇa; kaṣāya is lekhana-stambhana, grāhi-śoṣaṇa yet may increase pitta.
Vedantic Theme: Discernment and non-excess: even ‘useful’ measures have tradeoffs; wise application (yukti) prevents harm.
Application: Use bitter for fever, thirst, and ama/impurity with care for vāta dryness; use astringent for diarrhea/oozing conditions (grāhi) but avoid in pitta aggravation or excessive dryness/constipation.
Primary Rasa: shanta

This verse states that bitter taste stimulates digestion and helps reduce fever and thirst, while also acting as a cleansing and drying influence.
It describes astringent taste as scraping and constricting, binding/absorbent and drying, and notes that it can aggravate pitta.
Use bitter and astringent foods thoughtfully—bitter for supporting digestion and clearing heaviness, and astringent for reducing excess moisture—while avoiding overuse if pitta is already high.
