Bergamot Mint (Mentha citrata) Usually regarded as a cultivar of Mentha aquatica is also and variously known as Eau-de-cologne Mint, Horsemint, Lemon Mint, Lime Mint, Orange Mint, Pineapple Mint, Su Nanesi, Water Capitate Mint, Water Mint, Watermunt, Wild Water Mint, and in Central America Yerba Buena
It is not a rare mint but it is seldom available for purchase in its dried raw form as no industry exists to collect, dry and process it nor is there much demand to make such an industry viable so it has to be collected by hand by those who know it and in such small quantities that the required legislative procedures to check it for microbial or fungal infection and issue a certificate of authenticity and safety is prohobitively expensive, hence its rather expensive retail price.
For those that know it or have a requirement for it, however, it is well worth the price as to our knowledge it is yet again one of the items that is not stocked as a raw herb by the industry and can only be found easily at Luminescents
