#Avicen

• Abbasids — Members of the second great dynasty of caliphs who ruled the Islamic Caliphate (750–1258), centered in Baghdad. In the history of medicine, the Abbasid era represents the 'Golden Age' of Islamic medical sciences, characterized by the massive translation movement of Greek texts (Galen, Hippocrates), the founding of the first modern public hospitals (Bimaristan), the development of pharmacy as an independent discipline, and the emergence of illustrious medical encyclopedists such as Avicenna and Rhazes.
• Medicine during the Abbasid period — In a medical context, the term refers to the Abbasid era or dynasty (Abbasid medicine), a golden age in medical history (8th-13th centuries) which laid the foundations for modern hospitals (Bimaristan) and systematic pharmacology, and saw the translation of classical Greek texts by renowned physicians like Al-Razi (Rhazes) and Ibn Sina (Avicenna).
• Abutilon avicennae — The synonymous scientific designation for *Abutilon theophrasti*, popularly known in Romanian as 'teiușor' or 'crucea-pământului'. This annual herbaceous plant in the Malvaceae family, native to Asia, is recognized in modern agronomy as a severe invasive weed in row crops (corn, sunflower, soy), characterized by large, velvety, heart-shaped leaves and rigid, decorative, star-like seed capsules.
• Avicenna — A simplified graphic or phonetic variant used in charts, early medieval treatises, and some old encyclopedias for Avicenna, the Latinized name of Ibn Sina (980–1037), the legendary Persian philosopher, physician, logician, and polymath. Although modern Romanian has stabilized the form Avicenna, this variant reflects a direct adaptation based on early French philological patterns (Avicenne), keeping intact the historical importance of the author of the 'Canon of Medicine'.
