Herbal products have gained popularity over the past few decades. The reasons attributed to the rise in popularity are cheaper costs, easy availability, patient compliance and fewer side effects. However, liver toxicity following consumption of herbal remedies is on the increase. Thus, there is an urgent need to understand the mechanism of action of the herbal supplements on the liver. Occasionally, herbal supplements may also interact with conventional drugs. The present review focusses on a few herbs such as Aloe barbadensis, Atractylis gummifera, Centella asiatica, Mitragyna speciosa, Morinda citrifolia, Larea tridentata, Symphytum officinale, Teucrium chamaedrys and Xanthium strumarium, which are reported to cause hepatotoxicity in humans and animals. Prior knowledge on hepatotoxicity caused by herbs may be beneficial for clinicians and medical practitioners.

Curcumin is known for its potential health benefits; however, the evidence remains inconclusive regarding its necessity as a supplement for athletes during the preparatory phase of training. This study aimed to assess the effect of 6-week curcumin supplementation at a dose of 2g/day on selected inflammatory markers, blood count, and brain-derived neurotropic factor (BDNF) levels in middle-aged amateur long-distance runners during the preparatory period of a macrocycle. Thirty runners were randomly assigned to either a curcumin-supplemented group (CUR, n = 15) or a placebo group (PLA, n = 15).

Background: Randomised trials conducted from 2006 to 2021 indicated that vitamin D supplementation (VDS) was able to prevent severe COVID-19 and acute respiratory infections (ARI). However, larger randomised trials published in 2022 did not confirm the health benefits of VDS in COVID-19 patients.
Objective: To examine through a systematic review with meta-analysis the characteristics of randomised trials on VDS to COVID-19 patients and admission to intensive care unit (ICU), and of randomised trials on VDS for the prevention of ARI.

Recent studies show that inorganic arsenic (As) exerts a toxic effect on the intestinal epithelium, causing a significant increase in its permeability. This disruption of the epithelial barrier may favor the entry of contaminants or toxins into the systemic circulation, thus causing toxicity not only at the intestinal level but possibly also at the systemic level. The present study conducts an evaluation of the protective effect of various dietary supplements and plant extracts against the intestinal toxicity of inorganic As.

The medicinal value of herbal products is often rooted in their "traditional" use, recontextualized by modern biomedical research granting them certain medical uses. L. (Asteraceae), native to Mexico, exemplifies such historical developments of a species that played a key role in developing a major pharmacologically active compound - lutein.

Introduction: Coenzyme Q10 (CoQ10) is a fat-soluble vitamin-like quinone. The plasma levels of CoQ10 are reduced in patients with chronic kidney disease (CKD). CoQ10 supplementation can improve mitochondrial function and decrease oxidative stress in these patients.
