Cashew Apple and Nut: Edible Parts, Toxicity, and Health Benefits
Hello, science explorers! Today we’re going on a journey to discover the coriander plant. This feathery green herb is famous as a delicious kitchen ingredient, but did you know it has a cool science story? Let’s learn all about coriander, from its looks and life to its amazing uses. Get ready—by the end, you’ll be a coriander expert, just like Vedantu’s favourite plant detectives!
Let’s Meet the Coriander Plant – A Friendly Herb with Two Names!
What’s Its Scientific Name?
Coriander’s scientific name is Coriandrum sativum. It belongs to the Apiaceae family, which is the same family as parsley and carrots. Coriander is sometimes called cilantro—that’s the name for its fresh green leaves in many countries. This plant is native to the Mediterranean and Middle East. Today, it grows all around the world—maybe even in your kitchen garden!
Where Does Coriander Like to Grow?
- Coriander likes sunny places with light soil that drains water well.
- It grows best in places that are not too hot and not too cold.
- You will find coriander in Asia, Europe, America, and of course, all over India!
Exploring the Coriander Plant Parts – From Roots to Seeds
What Does the Plant Look Like?
Coriander is a small, feathery green herb. It grows fast, reaching about 30-60 cm (1–2.5 feet) tall. Let’s look at its parts one by one!
The Amazing Parts of Coriander
- Roots: Small, fibrous, and not usually eaten, but they help anchor the plant in the soil.
- Stems: Thin, hollow, green stems that grow upright and branch out.
- Leaves (Cilantro): Bright green and delicate. Young leaves are soft and flat with a feathery edge—they smell delicious and are used in salads, chutneys, and garnishes.
- Flowers: Tiny white or pale pink flowers grow in flat-topped bunches called umbels. These tiny flowers attract helpful insects!
- Fruits/Seeds: When the flowers dry, they turn into small, round seeds. We call these coriander seeds. They look brownish-yellow and smell sweet and spicy – perfect for cooking.
Did You Know?
Both the leaves and seeds of coriander are edible and tasty, but they taste very different! Isn’t that cool?
How Does Coriander Grow? – The Plant’s Life Story
Sprouting, Flowering, and Making Seeds
- You can plant coriander by putting the seeds in moist soil.
- In a week or two, green shoots pop up. Those become leaves (cilantro).
- Soon, the plant grows tall and produces flowers in umbrella-shaped clusters.
- After pollination (thanks to bees and insects), the flowers turn into seeds.
- These seeds fall or get collected, and the life cycle starts again!
Coriander’s Super Trick
If you pick the young leaves often, the plant gives you even more leaves! This is why chefs love snipping fresh cilantro in their gardens.

- Rich in Vitamin C and juice content
- Consumed fresh, juiced, or fermented in some regions
- Highly perishable; rarely sold in markets outside producing countries
3. Are cashew nuts poisonous if eaten raw?
Raw cashew nuts are not safe to eat due to toxic compounds in their shells. Main points:

- Can cause burns, allergies, and severe irritation
- Commercial cashew nuts are always processed (roasted or steamed) to remove toxins before consumption
4. Why are cashew nuts never sold in shells?
Cashew nuts are never sold in shells because the shell contains toxic oils. Reasons include:
- Shell oil contains skin irritants (like anacardic acid)
- Removing the shell requires special processing to ensure safety
- Prevents accidental poisoning or contact dermatitis in consumers
5. What is the difference between a cashew apple and a cashew nut?
The cashew apple is a swollen, edible pseudo-fruit, while the cashew nut is the true fruit (a seed inside a shell). Main distinctions:
- Cashew apple: Fleshy, juicy, high in Vitamin C, perishable
- Cashew nut: Kidney-shaped drupe attached below the apple; contains an edible seed after processing
- Nut shell is toxic; cashew apple is non-toxic but not widely transported
6. Where do cashew trees grow best?
Cashew trees grow best in warm, tropical climates with well-drained, sandy or laterite soils. Key regions include:
- India (especially Kerala, Goa, Andhra Pradesh, Maharashtra)

9. Can you eat the cashew plant or its leaves?
Only certain parts of the cashew plant are edible.
- Cashew apple: Edible and nutritious
- Cashew nut (processed): Edible after roasting
- Leaves, bark, other plant parts: Not consumed due to potential toxic compounds
10. Classify the cashew fruit based on its botanical structure.
The cashew fruit is botanically a combination of a pseudo-fruit and a true fruit. Structure explained:
- Pseudo-fruit (apple): Swollen, fleshy pedicel; not the true botanical fruit
- True fruit (nut): Kidney-shaped drupe attached under the apple; contains the edible seed
