In modern aromatherapy and balneoclimatology, the essential oil distilled from the needles of Abies procera is highly valued for its purity and intense balsamic scent, possessing proven clinical properties as a peripheral circulatory stimulant, excellent muscle analgesic, and powerful upper respiratory tract decongestant.
• Silver vine — Scientific name for a species of climbing vine in the Actinidiaceae family, native to the mountainous areas of China and Japan, commonly known as matatabi vine or silver vine. The plant features leaves that develop a silver-white tint during the growing season and produces elongated orange berries with a mildly spicy flavor. In East Asia, it is widely used in traditional medicine and as a highly potent euphoric stimulant for domestic and big coats, due to volatile compounds such as actinidine.
• Amphetamine — A synthetic chemical substance with an aromatic amine structure, possessing a potent stimulant effect on the central nervous system by enhancing the release of dopamine and norepinephrine.

• Analeptic — A substance or medication with a potent stimulating action on the central nervous system, structurally utilized to revitalize vital functions, particularly to stimulate respiratory and circulatory centers in the brainstem.

• Antihypnotic — Combating sleep, drowsiness, or the effects induced by hypnotic drugs; a central nervous system stimulant substance that induces wakefulness and alertness. In a clinical sense, it intervenes structurally by blocking sleep-promoting receptors or by stimulating the release of excitatory neurotransmitters such as dopamine and noradrenaline.
• Antisoporific — Counteracting, preventing, or eliminating drowsiness, lethargy, and torpor; a pharmacological substance or natural stimulant compound that induces alertness, keeping the body awake by blocking receptors responsible for sleep induction. Broadly, it refers to any external stimulus or activity that boosts mental vigilance and eliminates chronic fatigue.
