What happens when you eat rhubarb leaves?

Eating rhubarb leaves is not recommended and can be toxic. Rhubarb leaves contain high levels of oxalic acid, which can cause several adverse effects when consumed in significant amounts. Here's what happens when you eat rhubarb leaves:

Nausea and Vomiting: Oxalic acid can irritate the digestive tract, leading to nausea and vomiting.

Diarrhea: Oxalic acid can also cause diarrhea due to its laxative effect.

Cramping and Abdominal Pain: The irritation caused by oxalic acid can lead to abdominal pain and cramping.

Kidney Damage: Excessive consumption of oxalic acid can contribute to the formation of calcium oxalate crystals in the kidneys, increasing the risk of kidney stones and even kidney damage.

Mineral Absorption Interference: Oxalic acid can bind to minerals such as calcium, iron, and magnesium, reducing their absorption from the digestive tract. This can lead to deficiencies in these essential nutrients.

Skin Irritation: Rhubarb leaves contain anthraquinone, a compound that can cause skin irritation when handled or touched.

It's important to note that the concentration of oxalic acid in rhubarb leaves is higher than in the stalks, which are commonly used in culinary preparations. Therefore, it's crucial to avoid consuming rhubarb leaves, and only use the stalks for cooking purposes. Rhubarb stalks, when consumed in moderate amounts, are safe and can be enjoyed in various dishes.

If you accidentally ingest rhubarb leaves or experience any adverse symptoms after eating them, it's advisable to seek medical attention immediately.
