When it comes to citrus fruits, we often think of lemons, oranges, or limes. But there’s another ancient citrus fruit that deserves just as much attention — the citron. Known for its thick rind, refreshing aroma, and medicinal properties, citron has been valued for thousands of years across different cultures. From ancient Greece to modern Asia, citron has been used in everything from culinary recipes to traditional medicine. In this guide, we’ll explore everything about citron — its nutrition, health benefits, side effects, ways to consume it, and much more.
What is Citron?
Citron (Citrus medica) is one of the oldest citrus fruits known to humankind. It belongs to the Rutaceae family and is considered one of the original citrus species from which other varieties like lemons, limes, and oranges were later developed through hybridization.
Unlike its relatives, citron is large, oblong, and has a very thick, rough rind with minimal pulp inside. Its flesh is less juicy and quite sour or even slightly bitter, but the peel is rich in essential oils and antioxidants, making it highly valued in traditional medicine and the food industry.
Citron is often used to make candied peels, marmalades, teas, and natural remedies. In Asian countries like Korea and Japan, citron (locally known as Yuja or Yuzu) is popular for its healing properties, especially in soothing sore throats and boosting immunity.
