Hyssop is a plant. The parts that grow above ground are used to make medicine.
Hyssop is used for digestive and intestinal problems including liver and gallbladder conditions, intestinal pain, intestinal gas, colic, and loss of appetite. It is also used for respiratory problems including coughs, the common cold, respiratory infections, sore throat, and asthma.
Other uses include urinary tract infection (UTI), poor circulation, HIV/AIDS, and menstrual cramps.
Some people use hyssop as a gargle; in baths to cause sweating; and on the skin for treating skin irritations, burns, bruises, and frostbite.
In foods, hyssop oil and extract are used as a flavoring.
In manufacturing, hyssop oil is used as a fragrance in soaps and cosmetics.
