Cactus grandiflorus (Cact.)


Cactus grandiflorus, also known as large-flowered cactus or Queen of the Night, is a climbing cactus with large white flowers. Indigenous to the Antilles, Mexico and Central America it has been used as a health tonic for centuries by those living with it.

Cactus grandiflorus entered the homeopathic materia medica in the 1800s after it was found in homeopathic potencies to help painful constrictions and spasms from restricted blood flow, especially of the heart. The pain, whether of the heart of elsewhere is often severe and described as band-like, as if “grabbed by an iron fist”, like digging wire.

Common Uses

When the remedy matches the symptom profile, Cactus grandiflorus has the ability to treat conditions such as angina, arrhythmia, headache, colic, coughing or vomiting of blood, myocarial infarct, neuralgia, valvular disease.
