Ethnomedicinal Plants Used by Traditional Healers in Phatthalung Maneenoon et al. Journal of Ethnobiology and Ethnomedicine (2015) 11:43 DOI 10.1186/s13002-015-0031-5 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access Ethnomedicinal plants used by traditional healers in Phatthalung Province, Peninsular Thailand Katesarin Maneenoon1*, Chuanchom Khuniad1,2, Yaowalak Teanuan1,3, Nisachon Saedan1, Supatra Prom-in1, Nitiphol Rukleng1, Watid Kongpool1, Phongsura Pinsook1 and Winyu Wongwiwat1 Abstract Background: In rural communities of Thailand, traditional healers still play an important role in local health care systems even though modern medicine is easily accessible. Meanwhile, natural forests in Thailand which are important sources of materia medica are being greatly destroyed. This has led to an erosion of traditional Thai medicine. Furthermore, the concept of medicinal plant selection as medicine based on their tastes is still an important component of traditional Thai medicine, but no or little publications have been reported. Thus the aim of the present study is to collect ethnomedicinal data, medicinal plant tastes and relevant information from experienced traditional healers before they are lost. Methods: An ethnobotanical survey was carried out to collect information from nine experienced traditional healers on the utilization of medicinal plants in Phatthalung Province, Peninsular Thailand. Data were obtained using semi-structured interviews and participant observations. Plant specimens were also collected and identified according to the plant taxonomic method. Results: A total of 151 medicinal plants were documented and 98 of these are reported in the study. Local names, medicinal uses, parts used, modes of preparation, and the relationship between ailments and tastes of medicinal plant species are presented. Conclusions: This research suggests that traditional healers are still considered important for public health among Thai communities and that many people trust the healing properties of medicinal plants. In the future, it is hoped that traditional Thai medicine will be promoted and therefore will help reduce national public health expense.

  • Rosary Pea Abrus Precatorius (L.) Fabaceae
    InvasiveInvasive SpeciesSpecies ManagementManagement PlansPlans forfor FloridaFlorida Rosary Pea Abrus precatorius (L.) Fabaceae INTRODUCTION Rosary pea has been widely used in Florida as an ornamental plant for many years. The native range of rosary pea is India and parts of Asia, where this plant is used for various purposes. The roots of this plant are used to induce abortion and relieve abdominal discomfort. The seeds of this plant are so uniform in size and weight that they are used as standards in weight measurement. The seeds can also be used to make jewelry. Interestingly, one of the most deadly plant toxins, abrin, is produced by rosary pea (Abrus precatorius). Studies have shown that as little as 0.00015% of toxin per body weight will cause fatality in humans (a single seed). Interestingly, birds appear to be unaffected by the deadly toxin as they have been shown to readily disperse rosary pea seed. DESCRIPTION Rosary pea is a small, high climbing vine with alternately compound leaves, 2-5 inches long, with 5 to 15 pairs of oblong leaflets. A key characteristic in identifying rosary pea is the lack of a terminal leaflet on the compound leaves. The flowers are small, pale, and violet to pink, clustered in leaf axils. The fruit is characteristic of a legume. The pod is oblong, flat and truncate shaped, roughly 1½ - 2 inches long. This seedpod curls back when it opens, revealing the seeds. The seeds are small, brilliant red with a black spot. These characteristics give the plant another common name of crab’s eyes. IMPACTS Rosary pea is found throughout central and southern Florida, including Marion, Lake, Palm Beach, and Manatee counties.

Abstract The seed of Croton tiglium L. (SCT) is a well known folk medicine. In China, it has used to treat gastrointestinal disorders, intestinal inflammation, rheumatism, and so on. Previous studies established its purgative and inflammation properties. In addition, the effects of essential oil of SCT on intestinal transit and gastrointestinal tract has been studied. In the present study, we evaluated the antinociceptive effect of SCT through the writhing test in mice, investigated the effects of it on spontaneous smooth muscle contractions of isolated rabbit jejunum and examined the in-vitro results through the in-vivo small intestine propulsion. We further investigated the possible compounds using HPLC-MS, and six compounds were tentatively identified as phorbol esters. Furthermore, the possible fragmentation pathways of phorbol esters were proposed, and we also detected the possible compounds in the active parts. Keywords: Croton tiglium L; Intestinal propulsion; Smooth muscle; Rabbit jejunum; Antinociceptive; Phorbol esters.

The environmental sensitivity of Miami-Dade County is underscored by the fact that the urban developed area of the County portion lies between two national parks, Everglades and Biscayne National Parks, and the Florida Keys National Marine Sanctuary. The close relationship of tourism to the preservation of Miami-Dade County's unique native plants, fish, wildlife, beaches and near shore water quality is closely related to the continued success of the County’s tourism industry. and as such preservation So, natural resource preservation in Miami-Dade County has been recognized as an economic as well as environmental issue. The close proximity of an expanding urbanized area to national and State resource-based parks, and over 6,000 acres of natural areas within County parks, presents a unique challenge to Miami-Dade County to provide sound management. In addition, many experts suggest that South Florida will be significantly affected by rising sea levels, intensifying droughts, floods, and hurricanes as a result of climate change. As a partner in the four county Southeast Florida Regional Climate Change Compact, Miami-Dade has committed to study the potential negative impacts to the County given climate change projections, and is working to analyze strategies to adapt to these impacts and protect the built environment and natural resources. 2. The County has addressed this is also working to address these challenges by in several ways including working closely with other public and private sector agencies and groups to obtain a goal of sustainability.

    Herbal medicine is considered as the oldest form of medicines. Herbal Medicine is the oldest form of medicine and has at one time been the dominant healing therapy throughout all cultures and the peoples of the world. The first examples of the use of herbs as medicines date back to the very dawn of mankind. Archaeologists have found many evidences of the use of herbs by Neanderthal man in Iraq some sixty thousand years ago. All of the ancient civilizations – the Mesopotamian, Egyptian, Greek, Chinese, Indian and Roman used herbs as an integral part of their various medical systems. The first famous Herbalist, who stressed the importance of nature in healing, was Hippocrates, known as the “Father of Medicine”. It is on the long and continuous history of herbs as medicine, together with knowledge taken from modern scientific research, that today’s herbalism is based. The Philippine Institute of Traditional an Alternative Health Care has approved the 10 most common herbal medicines and as approved by the Department of Health. Acapulpo.
