The fragrant herb is also known as Blue Giant hyssop, Fragrant Giant hyssop and licorice mint.
Anise hyssop has been used by Native Americans as a breath-freshener, as a tea and as a sweetener. An infusion of the herb was used for chest pains, and the roots were used for coughs. Agastache is used in Chinese prescriptions for heatstroke, headache, fever, and angina.
Be careful if you have pets. Hyssop oil is toxic to dogs and other animals when ingested. It is used topically to prevent Lyme disease in dogs when applied to tick bites. Consuming the plant in large doses can cause respiratory tract irritation and seizures.
