Comestibilité

• Jeunes feuilles - crues ou cuites [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].

Usages médicinaux

• 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].

Culture

Propagation

• Graines - semez au printemps sous serre et recouvrez à peine les graines .
• 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 .
• Plantez les à la fin du printemps ou au début de l'été [K].
• Division au printemps .
• 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 .
