European spindle (Euonymus europaeus) is a striking hedgerow shrub with pink capsules and vivid orange arils. In gardens it turns heads; in medicine it raises caution. Historically, parts of the plant appeared in folk remedies as a purgative or external wash, and modern lab work has profiled unusual constituents (notably dihydro-β-agarofuran–type sesquiterpene–pyridine alkaloids and a fruit lectin). Yet there...

At the...
Euphorbia cyparissias: Risks, Side Effects, Folk Uses, and Poison Prevention
Euphorbia cyparissias—better known as cypress spurge—is a low, lime-green perennial in the spurge family whose showy bracts belie a harsh truth: the plant’s milky latex is powerfully irritant.

Some small trials suggest modest benefits for specific symptoms (for example, hot-flash severity), while rigorous reviews...
Evodia rutaecarpa Extract: Top Health Benefits, How to Use, and Potential Side Effects
Evodia rutaecarpa (also called Tetradium ruticarpum, Euodiae Fructus, or “Wu Zhu Yu”) is a traditional East Asian herb used for digestive discomfort, headaches, and abdominal cold. Modern extracts concentrate its alkaloids—most notably evodiamine and rutaecarpine—along with limonoids and related constituents.

But human data are limited, and quality...
Exogenous Ketones: Benefits, Uses, Dosage, Safety, and Side Effects Guide
Exogenous ketones are drinkable or powdered compounds that raise blood β-hydroxybutyrate (BHB) without fasting or strict carbohydrate restriction. They come mainly as ketone salts (BHB bound to minerals), ketone esters (compounds that release BHB after digestion), and 1,3-butanediol (a BHB precursor). In minutes, these products can elevate circulating BHB to “nutritional ketosis” levels, shifting fuel use and sometimes altering...
Exorphins: Key Benefits, Mood Effects, Food Sources, Dosage, and Safety Risks
Exorphins—also called food-derived opioid peptides—are tiny fragments released when certain proteins (most famously in dairy and wheat) are digested. Because these peptides can bind to the body’s opioid receptors, they may influence gut motility, pain perception, mood, and immune signaling. Interest has grown around casomorphins from milk (especially the β-casomorphin-7 or “BCM-7” fragment) and gluten exorphins from wheat and...
