Article Abstract
Herbal teas have potential health benefits, but they also contain a variety of pesticides and pesticide transformation products (PTPs) that might brings health risks. Our study maps the pesticides and PTPs in two herbal teas (chrysanthemum and Lusterleaf Holly) from two main producing areas in China. Almost all 122 samples contain pesticides, with concentration ranging from 0.0005 to 10.305 mg/kg. Nearly 40% carbendazim and imidacloprid in chrysanthemum teas and λ-cyhalothrin in Lusterleaf Holly have higher concentration levels than the values permitted in EC Regulation No. 396/2005. Distinct distributions of pesticides were found in different teas and production areas. Eight PTPs were identified along with their parents, and were confirmed using a biosynthetic strategy. Acute, chronic and cumulative health risk assessments of pesticides revealed acceptable results. Our study uncovers the profile of pesticides in herbal teas, and provides new insight into discovering the potential environmental pollution and food contaminants.

Tea trichomes, rich in secondary metabolites, are hypothesized to significantly influence white tea aroma, yet their biochemical contributions remain unclear. This study investigated the volatile profiles of tea trichome and tea body across six white tea samples using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and multivariate statistical analysis. Comparative analysis revealed significant differences in the volatile profile between tea trichome and tea body in all tested samples, with major differences lying in the content of volatile components.

Over the past ten years, plastic pollution has become a prominent and concerning environmental problem that our society must address. This study focuses on packaged herbal tea, investigating the prevalence and effects of microplastics (MPs) on selected herbal teas (green tea, sage tea, linden tea, and chamomile tea). This study offers the first information on MP pollution in four packaged herbal teas from five Turkish brands (A, B, C, D, and E).

Background: Idiopathic mesenteric phlebosclerosis (IMP) is a rare condition that causes ischaemic colitis, has various clinical manifestations, and may even be asymptomatic, often resulting in clinical misdiagnosis.
Case Summary: We report the case of a 44-year-old woman with chief complaints of abdominal pain, vomiting and decreased defecation. One year prior, the patient was asymptomatic and therefore misdiagnosed with inflammatory bowel disease based on incidental findings on an abdominal computed tomography (CT) scan.

The use of teas made from locally cultivated Artemisia annua to fight malaria in remote areas where access to care is difficult is a matter of debate. This study aimed at document differences in the composition of A. annua teas cultivated in Benin to be sold as antimalarial teas, and in France, and their impact on antiplasmodial activity.
