Note 388 — PART II. DR. COVEL’S DIARY. (continued 4)
Reading edition
Dr. Covel here probably refers to the tribulus terrestris, a caltrap, which is supposed to be the tribulus translated “thistle” in Matt. vii, 16, and Heb. vi, 8. It grows in quantities in the East, and is also known as “the Turkey plant”. It is very prickly, and the fruit is used medicinally.
