Soft drinks from Ancient India
Sauvīraka and tuṣodaka are sour fermented barley waters of classical Ayurveda. The recipe here is the purgative version in the Suśruta Saṃhitā, in which dehusked barley is soaked in an herbal decoction for seven days, dried and fried, then mixed with powdered herbs and left in an earthen pitcher. Tuṣodaka is made the same way from barley still in its husk, and both are used after six or seven nights, once they smell fermented.
| Well-threshed, dehusked barley | For sauvīraka; tuṣodaka uses unthreshed barley in its husk[sushruta-44] |
| Trivṛt roots, the Vidārigandhā group, the major Pañcamūla, Mūrvā, Śārṅgaṣṭā, Sudhā, Haimavatī, Triphalā, Ativiṣā and Vacā | Mixed and split in two; one half is boiled to a decoction, the other ground to powder[sushruta-44] |
| Fried barley and the powdered herbs3 parts barley to 1 part powder | Soaked together in the cold decoction[sushruta-44] |
| Starter | spontaneous |
Total time across the recorded steps: 13 days – 14 days
What changes: Half the herbs are boiled into a decoction and the other half are ground to powder
The herbs are mixed and split into two equal parts. One part is boiled into a decoction and the other is ground to powder. Output: herb decoction and herb powder.

Sauvīraka and tuṣodaka are sour fermented barley waters of classical Ayurveda. The recipe here is the purgative version in the Suśruta Saṃhitā, in which dehusked barley is soaked in an herbal decoction for seven days, dried and fried, then mixed with powdered herbs and left in an earthen pitcher. Tuṣodaka is made the same way from barley still in its husk, and both are used after six or seven nights, once they smell fermented. Made in 5 steps over 13 days – 14 days. The longest step, soak the dehusked barley in the decoction, takes 7 days (Suśruta Saṃhitā 1907).
| Main step | 7 daysReported[sushruta-44] | Soak the dehusked barley in the decoction |
|---|
Sauvīraka is made from dehusked barley that is soaked, dried and fried before it ferments. Tuṣodaka keeps the husk on, and its barley is boiled in a cloth bag before fermenting.
The recipe here is a purgative medicine, not a table drink. A review of Ayurvedic fermented preparations (sandhana kalpana) notes that earthen fermenting pots can break and that contamination is possible even after careful preparation. That is a general remark about the class, not a test of sauvīraka.
Every number is labelled with how it is known. How this atlas is made
Suśruta Saṃhitā, Sūtrasthāna chapter 44, on purgative recipes, read in Kaviraj Kunja Lal Bhishagratna's 1907 English translation. The same chapter gives a purgative surā, which is ready when it smells of honey.
