Star of Bethlehem

Also known as: Star of Bethlehem, Dame d'Onze Heures, Estrella de Belén, Étoile de Bethléem, Étoile de Marie, Nap-at-noon, Ornithogale en Ombelle, Sleepydick, Snowdrop, Ornithogalum umbellatum

Overview

Star of Bethlehem (Ornithogalum umbellatum) is a perennial plant native to Europe and parts of Asia, known for its star-shaped flowers that bloom in early spring. Historically, it has been used in traditional medicine, particularly for heart conditions, but this is considered unsafe due to the presence of toxic cardiac glycosides. These compounds, similar to digoxin, can affect heart function. The plant grows from bulbs and is identifiable by its white, star-like flowers. Due to its toxicity, Star of Bethlehem is not recommended for self-treatment, and any potential medicinal use should be under strict medical supervision. Research on this plant is limited, and the available evidence is largely anecdotal, emphasizing the need for caution.

Benefits

There is a lack of scientific evidence to support any health benefits of Star of Bethlehem. Anecdotal reports suggest potential benefits for heart conditions, but these are not supported by rigorous clinical trials. The plant contains cardiac glycosides, which can affect heart function, but the risks associated with these compounds outweigh any potential benefits. No population-specific benefits have been established, and there are no quantifiable effect sizes or clinical significance due to the absence of formal studies. Therefore, the use of Star of Bethlehem for any health condition is not recommended without medical supervision.

How it works

Star of Bethlehem contains cardiac glycosides that act similarly to digoxin, a medication used to treat heart conditions. These glycosides affect heart function by increasing the force of cardiac contractions and slowing the heart rate. The primary biological pathway involves interaction with cardiac glycoside receptors, mainly affecting the cardiovascular system. However, due to the potential for toxicity, the use of Star of Bethlehem is not recommended without strict medical supervision. The absorption and bioavailability of these compounds are not well-studied, adding to the uncertainty of its effects.

Side effects

Star of Bethlehem is considered unsafe for use as a supplement due to its toxic cardiac glycosides, which can cause life-threatening side effects. Potential side effects include irregular heartbeat and other cardiac issues. Due to safety concerns, common, uncommon, and rare side effects are not well-documented. Drug interactions are possible, particularly with cardiac medications. Contraindications include pregnancy, breastfeeding, and individuals with heart conditions without medical supervision. Avoid use in all populations due to significant safety risks. Symptoms of overdose may include nausea, vomiting, diarrhea, and severe cardiac arrhythmias, requiring immediate medical attention.

Dosage

Due to significant safety concerns, no dosage guidelines are established or recommended for Star of Bethlehem. There is no minimum effective dose, optimal dosage range, or maximum safe dose identified. Timing considerations and form-specific recommendations are not applicable. Absorption factors are not well-studied. The use of Star of Bethlehem is not recommended without strict medical supervision due to the risk of severe adverse effects.
