Citron

The citron is a big fruit.

It looks like a lemon. It has a very thick skin. The skin is very strong.

This fruit has a very strong smell. People use it for perfume. It is also used in food. Some citrons look like fingers.

This fruit is very old. It helped make other fruits like lemons. It is a special fruit from long ago.

The citron is a large, fragrant fruit.

It looks like a lemon, but it is much bigger. The fruit has a thick, leathery rind. Inside the rind is a white part called albedo. This part is very thick and hard.

The citron is a very old plant. It is one of the original citrus fruits. Other fruits, like lemons and many limes, came from it.

Some citrons have a strange shape. One kind is called Buddha's hand because it looks like fingers.

The citron tree is a small tree or shrub. It has green leaves that smell like lemons. The tree grows all year long. It blooms many times each year. However, the tree is fragile. It can be hurt by frost. People use the fruit in many ways. They use it for perfume and medicine. In some religions, the fruit is used for special rituals. For example, it is important during the Jewish holiday of Sukkot.

The citron is a large and very fragrant citrus fruit.

It looks a lot like a lemon, but it is much bigger. This fruit is special because it is one of the original citrus types. Other fruits like lemons and many limes were made from it. This happened through a way called hybridization.

In this process, different plants are crossed to make new ones. The citron is often the male parent in these citrus mixes. Even though citrons look very different, they are all closely related.

People use the fruit for many things. They use it in cooking, for making perfume, and for medicine. It is also used in religious rituals and offerings.

Inside the fruit, there is a thick white part called the albedo.

This albedo is very hard and thick. The outer part of the rind is thin and smells very strong. The pulp inside can be sour or even sweet. Some types of citron do not even have much pulp at all. The fruit can be shaped like an oval or a long shape. Some varieties even look like they have fingers. This specific kind is often called Buddha's hand.

The color changes from green to a yellow-orange as it gets ripe. If you do not pick it, it stays on the tree. The tree is a small shrub or a small tree. It has green leaves that smell like lemons. The tree is very strong and grows all year. However, it is fragile and can be hurt by frost.

People have known about the citron for a very long time.

Archaeologists found drawings of the fruit in Egypt from 3,500 years ago. It was also grown in Sumer during the 3rd millennium BC. Ancient writers like Theophrastus and Pliny the Elder wrote about it. Theophrastus said the fruit was very fragrant. He said people used it to keep moths away from clothes. He also said the smell could make breath smell better. Pliny called the tree the "Assyrian" tree. He noted that some people loved the smell while others did not. These old stories show how important the fruit has always been.

Scientists believe the citron originally came from the foothills of the Himalayas. It was not actually from a place called Media. The name comes from an old belief about where it lived. The fruit was grown near the Caspian Sea for a long time. Some say Alexander the Great helped spread it to Europe. He and his armies moved the fruit toward Greece and Italy. Today, we know the citron is a single species. Genetic tests show three main groups of these plants. One group comes from the Mediterranean and another from China. The Chinese group includes the fingered varieties.

You might see the citron used in many parts of the world today.

In the Jewish holiday of Sukkot, it is called an Etrog. It is paired with palm fronds during this special time. In Indonesia, people make a sweet treat called Succade. They use a variety called 'Macarpa' to make this. This fruit can grow to be 2.5 kilograms in mass. To make it sweet, they treat the bitter parts with salt first. The name 'citron' comes from the Latin word 'citrus.' This is the same root used for the scientific name. It is a fruit that connects many different cultures and histories.

The citron, known scientifically as *Citrus medica*, is a large and highly fragrant citrus fruit. It is distinguished by a thick, coarse rind that sets it apart from many other citrus varieties. While it may resemble a lemon, the citron is generally much larger in scale. This fruit holds a vital place in botanical history because it is one of the original citrus species. Through processes like natural hybrid speciation or artificial hybridization, the citron helped create many other citrus types. In fact, the citron often serves as the male parent in these citrus crosses. This makes it a foundational ancestor for many fruits we eat today, such as lemons and various limes.

The anatomy of a citron is quite unique compared to other fruits. The rind is leathery, furrowed, and adheres closely to the fruit. Inside this rind is a very thick, white, and hard layer called the albedo. The outermost layer of the rind is thin and carries an extremely powerful fragrance. The inner pulp can vary greatly; it may be highly acidic, quite sweet, or in some varieties, almost entirely pulpless. The fruit's shape is also highly variable due to how the albedo forms. It can be ovate, oblong, or even ribbed and warted. Some specific varieties, such as the "Buddha's hand," feature long, finger-like segments.

Biological studies show that all citron cultivars are closely related genetically. Scientists use genetic analysis to divide these cultivars into three distinct clusters. One cluster is Mediterranean in origin and is thought to have come from India. The other two clusters are predominantly found in China. One of these Chinese clusters represents the fingered citron varieties, while the other consists of non-fingered types. The citron tree itself is a vigorous, evergreen shrub or small tree. It features long spines at the leaf axils and lemon-scented leaves. Because the tree has almost no dormancy and blooms several times a year, it is extremely sensitive to frost.

The history of the citron stretches back thousands of years. Archaeological evidence suggests the fruit was cultivated in Sumer as early as the 3rd millennium BC. An Egyptologist named Victor Loret identified depictions of the fruit at the Karnak Temple, dating back approximately 3,500 years to the time of Thutmosis III.

Ancient writers also documented its many uses. The Greek philosopher Theophrastus noted that the fruit and leaves were so fragrant they could repel insects and keep clothes smelling fresh. He also suggested the fruit could be used to improve breath. The Roman writer Pliny the Elder called the tree the "Assyrian" tree. He noted that while some people disliked the bitter smell, others esteemed it highly. He even recorded that the pips were used in the East to season ragouts and sweeten the breath.

While its scientific name *Citrus medica* suggests an origin in Media, researchers believe this is not entirely accurate. The name likely comes from an old belief that the fruit originated in the kingdom of the Medes. Instead, the citron is thought to have been native to the southeast foothills of the Himalayas. It was likely cultivated along the shores of the Caspian Sea as it moved toward the Mediterranean basin. Some historians suggest that the armies of Alexander the Great helped spread the fruit westward into Greece and Italy.

Today, the citron remains culturally significant in many different ways. In Judaism, the fruit is known as an Etrog and is essential for the harvest holiday of Sukkot. It is often paired with lulavim, which are date palm fronds, during religious rituals. In other parts of the world, the citron is used for its culinary and medicinal properties. For example, Dutch merchants import a candied variety called Succade from Indonesia. This specific variety, *Citrus medica* 'Macrocárpa', can reach a massive weight of 2.5 kilograms. To remove its natural bitterness, the thick albedo undergoes a salt treatment before being processed into confectionery.
