Of the 7 traditional claims we have checked in this area, 3 find at least partial support in research.
Ayurveda
India · over 3,000 years
Ayurveda does prescribe morning sun. Atapa sevana, deliberate sunbathing, sits in the daily routine as a practice for strength and vitality, and it is old enough to predate any way of explaining why it might work. But…

PartialModern research confirms that vitamin D deficiency is widespread and directly causes nutritional rickets in children and osteomalacia in adults, by impairing calcium absorption and bone mineralisation. Breastfed infants…
TCM
China · over 2,000 years
Chinese medicine reads brittle, failing bones as depleted Kidney essence — the Kidney governs the bones — and answers with tonifying foods and moderate sun exposure. That is a genuine traditional account of weak bones,…

PartialThe gentle sun exposure this tradition prescribes now has a mechanism behind it: modern research confirms that vitamin D deficiency is widespread and directly causes nutritional rickets in children and osteomalacia in…
Japanese Kampo
Japan · since the 7th century
Japan has a codified massage of its own. Anma has been taught from dedicated manuals since the Edo period — Fujibayashi Ryohaku's Anma Tebiki among them, still catalogued in the National Diet Library…

DisputedA randomised trial of anma in forty cancer survivors found improvement in fatigue and insomnia, but nobody has tested it for the eyes, and the technique deliberately leaves out the oil this practice depends on.…
Korean Medicine
Korea · Dongui Bogam (1613)
Korean medicine did more than use fermented things — it made them. The Dongui Bogam, compiled at the Joseon court in 1613 under the physician Heo Jun, lists sinkok (神麴), a medicinal leaven, in its materia medica volume…

Not yet studiedNone of these Korean ferments has ever been tested on human skin, and the fibre trial above uses a different substance entirely, so the tradition's own remedies stay unverified even where its instinct to look inward has…
Unani
Greco-Persian lineage · since Avicenna
Avicenna gives friction a full section of the Canon's first book and grades it with some care: hard friction braces the body, soft friction relaxes it, repeated friction thins it, and the restorative kind, given after…

PartialUnani prescribes oil massage for the very fatigue this article is about, but never for the eyes, and no trial has tested the Unani version. PMID:29723235
European Herbalism
Europe · centuries of folk use
Rickets is the one disease on this page that European herbalism knew by name and worried about openly. Culpeper's herbal of 1653 mentions it thirty-one times, and the company it keeps is consistent: the spleen stands…
Read the article →What the science says
DisputedThe modern account is not a refinement of the spleen theory but a replacement for it: rickets is caused by a lack of vitamin D, which impairs calcium absorption and bone mineralisation, and it is prevented by sunlight…
Tibetan Medicine (Sowa Rigpa)
Tibet · Sowa Rigpa
Tibetan medicine gives anointing a formal place rather than an incidental one. In the Four Tantras, the final tantra devotes a chapter to byug pa — anointing and massage — counting it among the five external therapies…

Not yet studiedA 423-patient trial of the Tibetan white-channel ointment measured motor recovery after stroke; nothing in this tradition has been tested for the eyes. PMID:40984831
Modern science is not a tradition. We list it separately — as an independent check on the claims above, not as one more voice among them.
Modern Science
Vitamin D deficiency has been linked to everything from depression to dizziness — but the research is more nuanced than the headlines suggest.
