Note 618 — INDIGO.
William Johnston translation
Ἔγχυλον means also juicy, or something that has a taste. Neither of these significations is applicable here, where the subject relates to a substance which is dry and insipid, or at any rate which can possess only a small degree of astringency. It must in this place denote an inspissated or dried juice; but I can find no other passage to support this meaning.
