🌍 Historical Overview:
Onion’s Role Across Civilizations
The onion (Allium cepa) is one of the oldest
cultivated vegetables known to humanity. Archaeological evidence suggests its
use over 5,000 years ago, primarily in Central Asia, Iran,
and Afghanistan. From the tombs of Egyptian pharaohs, who valued
its ring-like layers symbolizing eternity, to Greek athletes and Roman
gladiators who consumed it to build strength — onions were a part of daily
health rituals.
In Ayurveda, onion is considered a 'Rajasic' food that stimulates heat and energy. It is used for detoxifying the body, reducing phlegm, and aiding in digestion. In Traditional Chinese Medicine (TCM), onions are believed to disperse cold, improve circulation, and treat respiratory issues.
