Pada Prakshalana (Foot Bathing)
Pāda-prakṣālana is washing or soaking the feet, placed in the evening routine before sleep: ten to fifteen minutes in warm water with saindhava lavaṇa, optionally with a Triphalā decoction. The Aṣṭāṅga Hṛdaya's daily-regimen chapter directs that the feet be kept clean but does not describe this soak.
Self-care. This is a practice a person can do for themselves. Read the cautions before starting.
What it is
Pāda-prakṣālana is foot bathing, listed as part of dinacaryā, the daily regimen, and as something a person does for themselves.
What it involves
A soak of ten to fifteen minutes before sleep, in warm water with saindhava lavaṇa (rock salt). A Triphalā kvātha, decoction, is given as an optional addition.
No water temperature beyond “warm” is specified, and no frequency or length of course is recorded.
What is used
Saindhava lavaṇa, and optionally Triphalā as a decoction. No oils are part of the recorded procedure.
Where it comes from in the classical literature
The citation given is Aṣṭāṅga Hṛdaya Sūtrasthāna 2, which is indeed the Dinacaryā chapter, the daily regimen. Its topics run through waking in brāhma muhūrta, danta-dhāvana, añjana for the eyes, abhyaṅga, vyāyāma, udvartana, snāna and the sadvṛtta rules of conduct.
The feet appear there twice: abhyaṅga is to be applied with special attention to the head, the ears and the feet, and the conduct rules include keeping the feet and the bodily orifices clean. What is not in that chapter is the procedure described above, a warm salt-water soak of set length taken before sleep. Caraka Sūtrasthāna 5, the other classical daily-regimen chapter, similarly has pādābhyaṅga, foot massage, at verses 90 to 92, and not foot washing.
So the chapter is the right general home for the practice and does direct that the feet be kept clean, but the specific soak recorded here could not be traced to it.
Who should take particular care
Anyone with diabetes, peripheral neuropathy, or any reduced sensation in the feet. A published clinical report describes three patients with diabetic neuropathy who sustained full-thickness burns covering four to five per cent of body surface from hot-water foot baths. Because neuropathy blunts pain, the heat exposure continued unnoticed; presentation was delayed, and the series included secondary infection and amputation. The authors advise that thermal foot baths be avoided in this group, and that anyone who uses one anyway measure the water with a thermometer rather than by feel and limit immersion time.
Cautions
- If you have diabetes, peripheral neuropathy, or any loss of sensation in your feet, do not judge water temperature by feel. A published case series records three patients with diabetic neuropathy who suffered full-thickness burns from hot-water foot baths, with delayed presentation, secondary infection and amputation. The authors advise avoiding thermal foot baths altogether in this group, and if one is used, measuring the temperature with a thermometer and limiting immersion time.
- Do not soak broken skin: open cracks, ulcers, blisters or a foot infection need a clinician, not a salt bath.
- The record specifies only "warm" and gives no temperature. Erring cool is the safe direction.
- Dry the feet properly afterwards, including between the toes.
- No adverse events and no contraindications are recorded for this procedure in the source used here, which means it has not been assessed for them.

Classical source
Aṣṭāṅga Hṛdaya, Sūtrasthāna 2 (Dinacaryā) (as cited in the record; the specific procedure not located there) — not independently confirmed; treat the locus as approximate
Partly confirmed, so marked unverified. Aṣṭāṅga Hṛdaya Sūtrasthāna 2 is genuinely the Dinacaryā chapter and does concern the feet twice: abhyaṅga applied especially to head, ears and feet, and a sadvṛtta rule to keep the feet and the orifices clean. But two independent renderings of the chapter were checked and neither contains the procedure the record describes, a ten to fifteen minute warm-water soak with saindhava lavaṇa before sleep, nor any pre-sleep foot routine. Caraka Sūtrasthāna 5 was also checked as the other daily-regimen locus: it has pādābhyaṅga at vv. 90-92, not foot washing. The chapter reference is left as given because it is the correct general context, but the procedural detail is not sourced from it.
Common questions
- How long should I soak, and what goes in the water?
- The recorded method is ten to fifteen minutes in warm water with saindhava lavaṇa (rock salt), taken before sleep, with a Triphalā decoction as an optional addition. No temperature and no frequency are given.
- Is a foot soak actually described in the classical texts?
- Not in the form given here, as far as could be checked. Aṣṭāṅga Hṛdaya Sūtrasthāna 2, the daily-regimen chapter, directs that the feet be kept clean and that oil massage be applied especially to head, ears and feet, but it does not describe a warm salt-water soak before sleep. Caraka Sūtrasthāna 5 has foot massage rather than foot washing.
- Is a hot foot soak safe if I have diabetes?
- Treat it as unsafe without medical advice. Diabetic neuropathy dulls the sense of temperature, and a published report documents severe burns from foot baths in exactly that situation, including a case that ended in amputation. Clinicians advise avoiding thermal foot baths in neuropathy, and measuring water with a thermometer rather than by hand if one is used at all.

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same procedure is given, modified or withheld depending on your constitution, your agni, the season and what else you are already doing. A page cannot know any of that.
