Clove Overview
Clove is a spice commonly used in cooking and has a warm, sweet, and slightly bitter flavor. It is the dried flower bud of the clove tree, which is native to Indonesia. Clove has been used in traditional Chinese and Ayurvedic medicine to treat respiratory and digestive conditions as well as an analgesic and antispasmodic. It is also very commonly utilized in topical preparations as an antimicrobial and an analgesic (especially for tooth-related pain).
Tolvaptan Overview
-
Tolvaptan (Jynarque) is used to slow the worsening of kidney function in certain patients with autosomal dominant polycystic kidney disease (ADPKD; a certain type of inherited kidney disease). Tolvaptan (Jynarque) is in a class of medications called vasopressin V2 receptor antagonists. It works by increasing the amount of water released from the body as urine and decreases the growth of cysts in the kidneys. Removing fluid from the body and slowing the growth of cysts helps to slow the worsening of kidney function.

This monograph only gives information about tolvaptan tablets (Jynarque) to slow the worsening of kidney function in patients with ADPKD. If you are using this medication to treat low levels of sodium in the blood, read the monograph entitled tolvaptan (low blood sodium).
