This article treats Chinese medical theories and concepts as cultural constructs that arose as much from practice-oriented concerns as from socio-political negotiations within the medical field. It further explores the interface of the biological and cultural. It is often futile to investigate how Chinese medical descriptions relate to biological processes, because the local biologies that the ...

background: giardiasis is a one of the most prevalent intestinal parasitic diseases in human, treatment of this disease through medicinal plants is very important since parasite resistance to chemical drugs exists. thus, in this study, the in vitro anti-giardial activity of chloroformic extract of tanacetum parthenium and artemisia annua on cyst and trophozoite of giardia lamblia were separatel...

Parasitism remains a challenge in the effective and efficient management of ruminant livestock. Among different approaches proposed for better these parasites, present work carried out on farm Faculty Agronomic Sciences (FSA) located Sékou, focused effectiveness annual mugwort powder (Artemisia annua) gastrointestinal nematodes (Nematoda) cattle. The coprological analyses were made at Laborator...

Malaria is a vector-borne infectious disease caused by the protozoan Plasmodium parasites. Each year, it causes disease in approximately 515 million people and kills between one and three million people, the majority of whom are young children in sub-Saharan Africa. It is widespread in tropical and subtropical regions, including parts of the Americas, Asia, and Africa. Due to climate change and...

Artemisia species are one of the many traditional medicinal plants of Ethiopia used for the treatment of infectious and non-infectious health problems. In the present study, eight extracts prepared from leaves and aerial parts of four Artemisia species (Artemisia absinthium, A. abyssinica, A. afra, and A. annua) growing in Ethiopia were tested in vitro against bloodstream forms of Trypanosoma b...

The phytohormone abscisic acid (ABA) plays an important role in plant development and environmental stress response. Additionally, ABA also regulates secondary metabolism such as artemisinin in the medicinal plant Artemisia annua L. Although an earlier study showed that ABA receptor, AaPYL9, plays a positive role in ABA-induced artemisinin content improvement, many components in the ABA signali...

Plants synthesize a great variety of isoprenoid products that are required not only for normal growth and development but also for their adaptive responses to environmental challenges. However, despite the remarkable diversity in the structure and function of plant isoprenoids, they all originate from a single metabolic precursor, mevalonic acid. The synthesis of mevalonic acid is catalysed by ...

Artemisia annua is an important medicinal crop used for the production of the anti-malarial compound artemisinin. In order to assist in the production of affordable high quality artemisinin we have carried out an A. annua breeding programme aimed at improving artemisinin concentration and biomass. Here we report on a combining ability analysis of a diallel cross to identify robust parental line...
