Quassia amara, also known as Bitterwood or Surinam Quassia, is a homoeopathic medicine prepared from the wood of Picræna excelsa or Quassia amara, tropical plants native to Jamaica and Surinam. Belonging to the Simaroubaceae family, it is well known for its intensely bitter properties and its action on the digestive and nervous systems. This medicine is particularly valuable in treating intermittent fevers, intestinal worm infestations, and gastrointestinal complaints marked by heartburn, regurgitation, and sluggish digestion. Quassia amara is also noted for aiding mental clarity in states of dullness or absent-mindedness, supporting liver function, and relieving sensations of abdominal emptiness or internal heat. Its overall tonic effect makes it helpful in cases of fatigue, poor assimilation, and general weakness, especially where digestive derangement and feverish states coexist.
