A bottle can carry a familiar ingredient and still be completely unsuitable for the use someone has in mind. Nasya refers to administration through the nose in Ayurvedic practice. It should not be confused with smelling a flower, wearing a scented oil or using a prescribed nasal medicine.

A photograph or an online demonstration cannot assess an individual reader's circumstances. Do not improvise nasal drops from kitchen oils or unidentified herbal mixtures.

If the observer is unsure, leave that uncertainty in the account. Small distinctions of language can prevent a cultural description from becoming an unsafe instruction.
