• Aërangis biloba — A popular species of epiphytic orchid in the genus Aerangis, native to a wide range of tropical West and Central Africa. It is structurally recognized by its obovate leaves that feature an asymmetrically split tip forming two distinct lobes (bilobed), and by pendulous spikes bearing up to twenty star-like, white flowers with pale pink hues on their short spurs, heavily fragrant at night.
• Aerohydrotherapy — A complex therapeutic method used in rehabilitation medicine and balneoclimatology, based on combining the beneficial action of pure air baths or atmospheric currents with the external therapeutic applications of water (baths, showers, hydromassage) at various temperatures.
• Aerotherapy — A therapeutic method, hygienic treatment, or natural balneological procedure consisting of the guided and methodical exposure of the patient's body to the action of fresh air from specific geographic zones (sea, mountain, coniferous forests). This structural treatment stimulates blood oxygenation, regulates metabolism, strengthens the immune system, and alleviates chronic respiratory ailments or states of asthenia.
• Aesculus — A genus of woody plants, deciduous trees, and shrubs belonging to the Sapindaceae family (formerly Hippocastanaceae), distributed throughout the temperate regions of the Northern Hemisphere. These species are structurally characterized by palmate-compound leaves, large erect thyrsus-like inflorescences, and globose, often spiny capsular fruits containing large seeds popularly known as chestnuts.
• Aesculus hippocastanum — Scientific name of the horse chestnut, an imposing deciduous tree native to the mountainous forests of the Balkan Peninsula, widely cultivated as an ornamental plant in temperate zones. It is structurally recognized by its globose crown, white flowers with red or yellow spots grouped in erect panicles, and spiny capsules containing seeds rich in aescin, a substance extensively used in pharmacology to treat venous disorders.
• Aphid — The feminine structural variant of the noun 'afid'. It denotes an aphid or plant louse, a small, soft-bodied, sap-sucking insect that infests plants in dense colonies, causing severe agricultural damage and transmitting plant viruses.

Its leaves emit a strong, goat-like odor, and it is traditionally used for its anti-inflammatory, analgesic, and wound-healing effects, although it contains pyrrolizidine alkaloids toxic to the liver.
• Agerasia — A rare biological state characterized by the absence of visible clinical or physical signs of old age at an advanced age; an unusual preservation of vigor, youthful appearance, and cognitive functions despite chronological aging. It represents a phenomenon of extremely slow or genetically optimized senescence.
