A classic way of delaying drug resistance is to use an alternative when possible. We tested the malaria treatment Argemone mexicana decoction (AM), a validated self-prepared traditional medicine made with one widely available plant and safe across wide dose variations. In an attempt to reflect the real situation in the home-based management of malaria in a remote Malian village, 301 patients wi...

A rapid hydrostatic counter-current chromatography-thin-layer chromatography-electrospray-ionization time-of-flight mass spectrometry (CCC-TLC-ESI-TOF-MS) technique was established for use in seeking potent anti-Alzheimer's drugs among the acethylcholinesterase inhibitors in Argemone mexicana L. underground parts, with no need to isolate components in pure form. The dichloromethane extract from...

Fallback foods are often viewed as central in shaping primate morphology, and influencing adaptive shifts in hominin and other primate evolution. Here we argue that fruit of the tamarind tree (Tamarindus indica) qualifies as a fallback food of ring-tailed lemurs (Lemur catta) at the Beza Mahafaly Special Reserve (BMSR), Madagascar. Contrary to predictions that fallback foods may select for dent...

People consider herbal products as safe because of their natural origin, without taking into consideration whether these plants contain a toxic principle. This represents a serious health problem. A bibliographic search was carried out using published scientific material on native plants from Mexico, Central Am...

There is at present considerable agitation in the country over the adulteration of mustard oil with argemone oil. It has been fully realized that ingestion of mustard oil contaminated with argemone oil produces symptoms similar to those of epidemic dropsy. The experiments carried out in the field and the observations made by the various workers in this respect support the argemone contamination...

the disease from various parts of Bihar including Patna the capital town in late 1949 and early 1950. In the course of the steps taken to stop /the outbreaks, a large number of oil mills and wholesale mustard seed dealers' godowns were visited. Mustard seeds mixed with argemone seeds were found in only those samples imported from other states and in none of the indigenous samples. Doubts were r...

Mass mortality of stinging catfish, Heteropneustes fossilis, was observed in a fish farm of Kulgaria, Burdwan in West Bengal, India. The cumulative mortality rates reached up to 5% of the total fish in the farm per day. The clinical signs of the affected fish showed ulcers on the skin which gradually grew in size and progressed to form ulcerous dermatitis. Clinical signs of catfish experimental...
