What Is Rhubarb?
Rhubarb, scientifically known as Rheum rhabarbarum, is a perennial vegetable that is recognized for its long, thick stalks and large, triangular leaves.
It belongs to the genus Rheum and is classified as a vegetable, despite often being treated as a fruit in culinary contexts due to its sour taste.
The stalks of rhubarb are the part of the plant that is edible and can vary in color from light green to deep red, depending on the variety and maturity.
When eaten raw, they have a crunchy texture, but when cooked, they become tender. Typically, rhubarb stalks are harvested during the spring and early summer months.
Rhubarb is commonly used in cooking and baking to create pies, crisps, jams, sauces, and compotes. Its tart flavor complements sweet ingredients like sugar, honey, and berries.
However, it is important to note that the leaves of rhubarb contain oxalic acid, which can be harmful if consumed in large amounts. Therefore, it is essential to only consume the stalks and discard the leaves.
In conclusion, rhubarb is highly valued for its distinct flavor and versatility in the culinary world, providing a tangy component to various dishes and desserts.

Although rare, some individuals may experience allergic reactions to rhubarb, especially if they have existing sensitivities or allergies to other plants in the Polygonaceae family.
Symptoms of an allergic reaction may include itching, skin rash, swelling, difficulty breathing, or anaphylaxis. In case of suspecting an allergic reaction, it is important to promptly seek medical assistance.
5) Toxicity from Leaves
Rhubarb leaves have harmful substances such as oxalic acid and anthraquinones, making them unfit for consumption.
The consumption of rhubarb leaves can lead to various adverse effects, including nausea, vomiting, abdominal discomfort, breathing difficulties, seizures, and even death.
It is crucial to always remove and dispose of the leaves before utilizing rhubarb stalks for culinary purposes.
6) Pregnancy and Breastfeeding
