Zootherapeutic uses of animals excreta: the case of elephant dung and urine use in Sayaboury province, Laos.

Background: Despite a widespread aversion towards faeces and urine, animal excreta are used in traditional medicine in many countries since centuries, but records are scattered and few therapeutic uses have been accurately documented while in the current context of emerging zoonoses such records may be of major interest.

Methodology: In this study, we investigated the therapeutic uses that mahouts in Xayaboury province, Lao PDR make of elephant urine and faeces as well as of the brood chamber that beetles (Heliocopris dominus) fashion from elephant dung. Semi-structured interviews were conducted with mahouts on elephant diet, health problems and responses to disease, andwhether they use elephant products.

Wild food plants and fungi sold in the markets of Luang Prabang, Lao PDR.

Background: Open air markets hold an important position for ethnobiologists. In Southeast Asia, they are seriously understudied, in spite of their incredible biocultural diversity. In order to fill this gap we recorded plants and fungi sold in the open air markets of Luang Prabang, Lao PDR.

Discovery of the first succulent bamboo (Poaceae, Bambusoideae) in a new genus from Laos' karst areas, with a unique adaptation to seasonal drought.

Lush jungle flagship species, woody bamboos (Poaceae-Bambusoideae) are famed for their synchronous flowering as well as the extensive "bamboo forests" some species can form in tropical or temperate environments. In portions of their natural distribution, Bambusoideae members developed various adaptations to seasonality in environmental parameters, such as frost or seasonal drought. A new taxon, , described here, is extremely novel in showing the first documented case of succulence in bamboos, with its ability to seasonally vary the volume of its stem depending on the quantity of water stored.

Forest Fevers: traditional treatment of malaria in the southern lowlands of Laos.

Ethnopharmacological Relevance: Malaria is still a highly challenging public health issue in southern Lao PDR, with increasing cases of artemisinin resistance and Plasmodium vivax infections which are more complicated to treat. Traditional medicine has a long history of use in Laos, and is primarily practised by traditional village healers, who possess unique bodies of transmitted knowledge focused on herbal prescriptions, including those for the treatment of malaria. Villagers also use plants for healthcare in the home.

From plant selection by elephants to human and veterinary pharmacopeia of mahouts in Laos.

Ethnopharmacological Relevance: To what extent has animal observation contributed to the development of human pharmacopeias? We approach this question here through the study of mahouts' knowledge regarding the responses by elephants to their health problems, and the human medicinal uses of plants and the care of domestic animals that result from their observations.

Materials And Methods: 32 mahouts were interviewed in Thongmyxay district and 28 at the Elephant Conservation Center in the province of Xayabury. Interviews focused on the elephants' diet, health problems, plant items they consume in particular physiological or pathological contexts and the treatments that mahouts provide them.

Comparing medicinal plant knowledge using similarity indices: a case of the Brou, Saek and Kry in Lao PDR.

Background: Medicinal plant traditional knowledge is one of the most widely known traditional ecosystem services, as it provides primary healthcare, contributes to subsistence livelihoods, and for its potential value as a source of novel pharmaceuticals. People living in close contact with their surroundings for many generations are hypothesized to have developed, through trial-and-error, in-depth knowledge of ecosystems, biodiversity, and their management and utility. In the case of medicinal plant knowledge it could lead to an asymptotic climax or a constantly evolving equilibrium of cures with proven efficacy and those under assessment.

Steam sauna and mother roasting in Lao PDR: practices and chemical constituents of essential oils of plant species used in postpartum recovery.

Background: Fundamental in traditional postpartum recovery in Lao PDR is the use of hotbeds, mother roasting, steam sauna and steam baths. During these treatments medicinal plants play a crucial role, but little has been published about how the treatments are carried out precisely, which species are used, the medicinal properties of these species, and the medicinal efficacy of their chemical constituents.

Methods: Sixty-five interviews, in 15 rural villages, with women of 4 different ethnic groups were conducted to survey confinement rituals, and postpartum plant use and salience.

Traditions and plant use during pregnancy, childbirth and postpartum recovery by the Kry ethnic group in Lao PDR.

Background: Activities and diet during the postpartum period are culturally dictated in many Southeast Asian cultures, and a period of confinement is observed. Plants play an important role in recovery during the postpartum period in diet and traditional medicine. Little is known of the Kry, a small ethnic group whose language was recently described, concerning its traditions and use of plants during pregnancy, parturition, postpartum recovery and infant healthcare.

Plants used during pregnancy, childbirth and postpartum healthcare in Lao PDR: a comparative study of the Brou, Saek and Kry ethnic groups.

Background: In many Southeast Asian cultures the activities and diet during the postpartum period are culturally dictated and a period of confinement is observed. Plants play an important role in recovery during the postpartum period in diet, traditional medicine, steam bath and mother roasting (where mother and child placed on a bed above a brazier with charcoal embers on which aromatic plants are laid). This research focuses on the use of plants during pregnancy, parturition, postpartum recovery and infant healthcare among three ethnic groups, the Brou, Saek and Kry.
