Engystol

Engystol is a branded complex homeopathic medicinal product composed of highly diluted extracts of Vincetoxicum hirundinaria (Asclepias vincetoxicum, white swallow-wort) and elemental sulfur in multiple potencies, formulated primarily as oral tablets and injectable ampoules. It is developed and marketed by Biologische Heilmittel Heel as an over‑the‑counter remedy aimed at activating non‑specific immune defenses to reduce the severity and duration of viral respiratory infections, particularly colds and influenza‑like illnesses, and is also promoted more broadly for upper respiratory infections and recurrent viral conditions by “supporting” endogenous defense mechanisms rather than targeting specific viral proteins.[5][8][10][11][12]
