पानं पानीयं चाउषधेन व्याख्यातम् ॥ कZ_०१.२१.११ ॥
pānaṃ pānīyaṃ ca auṣadhena vyākhyātam ।
ເຄື່ອງດື່ມ ແລະ ນ້ຳດື່ມ ຕ້ອງຖືກຄວບຄຸມຕາມຂັ້ນຕອນດຽວກັນກັບຢາ (ມີການກວດສອບຢືນຢັນເທົ່າທຽມກັນ)។
Extension by analogy: once a strict control is defined for medicine, the same control is applied to beverages and water without restating the full procedure.
Because both are direct ingestion vectors; water is a high-frequency, low-suspicion channel for poisoning.
