Wood Apple: How To Eat & Benefits | Organic Facts
There are a few tropical fruits that can look or smell bewildering but have a faithful fan following worldwide, such as jackfruit and durian. Wood apple is one of these kinds of fruits but is yet to make its mark in many countries outside of Southeast Asia.
To make matters a bit more mysterious, wood apple is not just one fruit but a generic name for several trees of the Aurantioideae subfamily within the rue and the citrus family. Botanically, Aurantioideae are characterized by small trees or shrubs with fragrant white flowers and fruits that have either a granular peel or an extremely hard shell. In this article, we delve into details on the fruit of the tree – the wood apple. [1]

What Is A Wood Apple?
As mentioned above, wood apple is a generic name given to fruits that belong to trees from the Aurantioideae subfamily. Here are two fruits that are relatively well-known:
- Wood apple (Aegle marmelos): Commonly called bael fruit, this is an edible fruit from plants native to India. Other names for this variety are Bengal quince, golden apple, stone apple, holy fruit, and Japanese bitter orange.[2]
- Wood apple (Limonia acidissima): This is a fruit from trees native to Bangladesh, India, Pakistan, Sri Lanka, and Southeast Asia.
To add to the confusion, both the fruits are interchangeably called wood apples, bael fruit, bel, and even elephant apple in different regions of Southeast Asia. However, both can have different textures, fragrances, and tastes. Let’s find more.

Bael fruit is a round or oval fruit that may have a thin, hard, woody shell or a gray-green rind that turns more yellow when ripe. You can find bael fruit trees in many temple gardens in India as the tree is considered sacred and the leaves are often used in religious ceremonies. [3]

For a harder rind bael fruit, you may need to knock it a few times with the backside of a heavy knife. Once the rind cracks, you can gently pull it apart. [4]
The flesh of the bael fruit can range from a mild orange color to a caramel brown and is fragrant, reminiscent of honey, and bananas. The flesh contains seeds that have wooly hairs and some mucilage that hardens on drying. Bael fruit can be eaten and used in several ways:

It might be a good source of carotene, thiamine, riboflavin, niacin, and vitamin C. The fruit, bark, leaves, roots, and seeds have been extensively used medicinally in Ayurveda for thousands of years for stomach-related ailments, ulcers, tuberculosis, and hepatitis. Most of the research studies on the health benefits of bael fruit have been done in India. The most important bael fruit benefits are: [6] [7]

Word of Caution: Researchers have found that the fruit is generally safe to consume. However, too much of it can cause constipation in certain individuals. [13]
Wood Apple (Limonia acidissima)
Unlike bael fruit, the Limonia acidissima variety is a little less known worldwide. This variety of wood apples has an extremely hard graying green exterior and almost looks and feels like a moldy shaved coconut. The hard exterior is why this fruit has been called a wood apple. In some parts of the world, this fruit is called elephant apple because it is a favorite food of elephants. While most varieties are large in size (5 inches), there are other varieties that are much smaller and can have an acidic taste. [14]
