Edible Uses
Edible Parts: Leaves;  Seed.
Edible Uses: Condiment;  Tea.

Young leaves - raw or cooked[177]. A strong anise-like fragrance, they are normally used as a flavouring[183] or as an addition to the salad bowl[238]. We find them a bit coarse and too strong for use as a salad[K]. The leaves can be used as a tea substitute[183]. A pleasant flavour[238]. The seed is possibly edible[177]. No further details. The seed certainly should not be poisonous, but it is very small and its use would be very fiddly[K].

Korean mint is commonly used in Chinese herbalism, where it is considered to be one of the 50 fundamental herbs[218]. Considered to be a "warming" herb, it is used in situations where there is "dampness" within the digestive system, resulting in poor digestion and reduced vitality[254]. The leaves and stems are antibacterial, antifungal, aromatic, carminative, diaphoretic, febrifuge and stomachic[147, 176, 218, 238, 279]. They are used internally to improve the appetite and strengthen the digestive system[238], they relieve symptoms such as abdominal bloating, indigestion, nausea and vomiting[254]. They are also used to treat morning sickness[254]. The leaves are also used in the treatment of chest congestion, diarrhoea and headaches[218]. An infusion of the leaves is used in the treatment of angina pains[222]. The plant is used as a folk remedy for cancer, extracts of the plant have shown anticancer activity[218].

Cultivation details
Prefers a sunny sheltered position and a well-drained soil[200]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. The flowers are very attractive to bees[244].
Propagation
Seed - sow spring in a greenhouse and only just cover the seed. The seed usually germinates in 1 - 3 months at 13°c[133]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant out in late spring or early summer[K]. Division in spring. Fairly simple, if large divisions are used it is possible to plant them straight out into their permanent positions. Basal cuttings of young shoots in spring[111]. Harvest the young shoots when they are about 10 - 15cm tall and pot them up in a lightly shaded position in a greenhouse. They should root within 3 weeks and can be planted out in the summer or following spring.

"It is hardy to zone 8 and is not frost tender" - that's not true. Agastache rugosa grows in Russia Far East where winter can be -30 cold. I grow it in my garden in Slovakia which is approximately zone 5.
