Abstract [en]

The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. Whilst revising Amomum for the Flore du Cambodge, du Laos et du Viêtnam, we have proposed to conserve the name Amomum villosum Lour. with a recent collection from Laos, which was not included in the protologue, as its type. Our research on the use of Amomum focuses on the use of plants during pregnancy, parturition, postpartum recovery and infant healthcare among three ethnic groups, the Brou, Saek and Kry. The investigations aim to identify culturally important traditions that may facilitate implementation of culturally appropriate healthcare. Data were collected in Khammouane province, Lao PDR, through group and individual interviews with women by female interviewers. More than 55 plant species are used in women's healthcare, of which > 90 % are used in postpartum recovery. This wealth of novel insights into plant use and preparation will help to understand culturally important practices such as confinement, dietary restrictions, mother roasting and herbal steam baths and their incorporation into modern healthcare. Through chemical analyses of Amomum we have recorded compounds with antimicrobial, analgesic and sedative effects that point to an empirical development of the traditional treatments around childbirth. Essential oils of three species used in hotbed and mother roasting, Amomum villosum Lour. Amomum microcarpum C.F.Liang & D.Fang and Blumea balsamifera (L.) DC. were found to contain significant amounts of the following terpenes: b-pinene, camphor, bornylacetate, borneol, linalool, D-limonene, fenchone, terpinen-4-ol and a-terpinene.
