Τριπόλιον,
Tripolium; the root is hot in the third degree and acrid.
Commentary. We shall have an opportunity in our [Appendix] to discuss the question, whether or not this be the Turpeth of the Arabians, as has been often stated. We may just mention in this place, that Sprengel is inclined to refer it to the Plumbago Europæa, a plant which seems to agree very well with the characters of the present article, inasmuch as its root is peculiarly acrid. See Lindley (Veg. Kingd. 641.) Dioscorides says of it, that its root is hot to the taste, and that when drunk with wine it discharges water and urine from the belly, and that it is used as an alexipharmic. (iv, 133.) Galen and the other Greek authorities call it acrid to the taste and hot in the third degree. For the reason already stated we shall not enter upon an exposition of the views of the Arabians in this place.
Τρίχες,
Pili, Hairs, when burnt have similar powers to burnt wool.
Commentary. Our author follows Galen. The Arabians recommend burnt hairs as an application to foul ulcers, and the bite of a mad dog. See Avicenna (ii, 2, 191), and Haly Abbas (Pract. ii, 52, 552.)
Τρυγων θαλασσίη,
Pastinaca marina; its sting when pressed upon a weak tooth breaks it, and makes it fall out.
Commentary. We have treated of the Pastinaca marina in [Book V]. Scarifications of the gums with the sting of this fish in cases of difficult dentition are recommended by Marcellus Sideta and Pliny (H. N. xxxii, 26.)
