Rhubarb is a popular vegetable often used in pies, tarts, and other sweet treats. However, despite its widespread use, there are certain times when it’s not safe to eat rhubarb. In this article, we’ll explore the risks and precautions associated with consuming rhubarb, helping you to enjoy this delicious vegetable safely.
Understanding Rhubarb Toxicity
Rhubarb contains high levels of oxalic acid, a naturally occurring compound that can be toxic in large quantities. While the stalks of the rhubarb plant are safe to eat, the leaves contain high concentrations of oxalic acid and should be avoided.
The Dangers of Oxalic Acid
Oxalic acid is a powerful toxin that can cause a range of health problems, including:
- Kidney damage: Oxalic acid can damage the kidneys and increase the risk of kidney stones.
- Respiratory problems: Inhaling oxalic acid can cause respiratory problems, including coughing and shortness of breath.
- Gastrointestinal issues: Consuming oxalic acid can cause nausea, vomiting, and diarrhea.
When to Avoid Eating Rhubarb
While rhubarb can be a delicious and nutritious addition to your diet, there are certain times when it’s best to avoid eating it.
Pregnancy and Breastfeeding
Pregnant and breastfeeding women should avoid eating rhubarb, as the high levels of oxalic acid can pose a risk to the developing fetus or baby. Additionally, rhubarb can stimulate the uterus and cause contractions, which can be problematic during pregnancy.
Kidney Problems
Individuals with pre-existing kidney problems should avoid eating rhubarb, as the oxalic acid can exacerbate kidney damage. If you have kidney disease or are at risk of developing kidney stones, it’s best to limit your rhubarb consumption or avoid it altogether.
Gastrointestinal Issues
People with gastrointestinal issues, such as irritable bowel syndrome (IBS), may want to avoid eating rhubarb, as the high fiber content can exacerbate symptoms.
Medication Interactions
Rhubarb can interact with certain medications, including:
- Blood thinners: Rhubarb can increase the risk of bleeding when taken with blood thinners.

Precautions for Eating Rhubarb
While rhubarb can be a healthy addition to your diet, there are certain precautions to take when consuming it.
Only Eat the Stalks
Only eat the stalks of the rhubarb plant, as the leaves contain high levels of oxalic acid. Make sure to trim the leaves from the stalks before cooking or eating.
Cook Rhubarb Properly
Cooking rhubarb can help reduce the levels of oxalic acid. Make sure to cook rhubarb thoroughly, using plenty of water and sugar to balance out the flavor.
Consume in Moderation
Consume rhubarb in moderation, as excessive consumption can lead to an overload of oxalic acid. Limit your rhubarb intake to 1-2 cups per week.
Rhubarb Allergy and Intolerance
Some individuals may be allergic or intolerant to rhubarb, which can cause a range of symptoms, including:

When is rhubarb toxic to eat?
Rhubarb is toxic to eat when the leaves contain high levels of oxalic acid, a naturally occurring compound that can cause serious health issues if ingested in large quantities. The leaves of the rhubarb plant are particularly toxic, as they contain higher concentrations of oxalic acid than the stalks. While the stalks are safe to eat and are often used in pies and other desserts, the leaves should be avoided at all times.
It’s essential to note that the toxicity of rhubarb leaves can vary depending on factors such as the plant’s age, growing conditions, and time of year. However, it’s always best to err on the side of caution and avoid eating rhubarb leaves altogether. If you’re unsure whether a particular part of the rhubarb plant is safe to eat, it’s best to consult with a medical professional or a qualified gardening expert.
Can you eat rhubarb that has been sprayed with pesticides?
No, it’s not recommended to eat rhubarb that has been sprayed with pesticides. Pesticides can leave behind residues on the plant that can be toxic to humans if ingested. Rhubarb is a porous plant that can absorb pesticides easily, which can then be transferred to the stalks and leaves. Eating rhubarb that has been sprayed with pesticides can increase your risk of exposure to these toxic chemicals.
If you’re growing your own rhubarb, it’s essential to use organic gardening methods to avoid exposing the plant to pesticides. If you’re purchasing rhubarb from a store or farmer’s market, look for certified organic produce to minimize your exposure to pesticides. Always wash your rhubarb thoroughly before eating it, and consider soaking it in a mixture of water and vinegar to remove any pesticide residues.
Is it safe to eat rhubarb that has been contaminated with heavy metals?
No, it’s not safe to eat rhubarb that has been contaminated with heavy metals. Heavy metals such as lead, mercury, and arsenic can accumulate in the soil and be absorbed by the rhubarb plant. Eating rhubarb that has been contaminated with heavy metals can increase your risk of exposure to these toxic substances.
If you’re growing your own rhubarb, it’s essential to test your soil regularly for heavy metal contamination. If your soil is contaminated, consider using raised beds or containers to grow your rhubarb. If you’re purchasing rhubarb from a store or farmer’s market, look for produce that has been grown in areas with low levels of heavy metal contamination. Always wash your rhubarb thoroughly before eating it, and consider soaking it in a mixture of water and vinegar to remove any heavy metal residues.
Can you eat rhubarb if you have kidney stones?
No, it’s not recommended to eat rhubarb if you have kidney stones. Rhubarb contains high levels of oxalic acid, which can increase your risk of developing kidney stones. Oxalic acid can also exacerbate existing kidney stones, making them more painful and difficult to pass.
If you have kidney stones, it’s essential to avoid eating rhubarb and other foods that are high in oxalic acid. Instead, focus on eating foods that are low in oxalic acid and rich in nutrients that can help to prevent kidney stones. Consider consulting with a healthcare professional or a registered dietitian to develop a personalized diet plan that meets your needs.
Is it safe to eat rhubarb if you’re pregnant or breastfeeding?
While rhubarb is generally considered safe to eat in moderation, it’s essential to exercise caution if you’re pregnant or breastfeeding. Rhubarb contains high levels of oxalic acid, which can increase your risk of developing kidney stones. Additionally, rhubarb may stimulate the uterus and cause contractions, which can be problematic during pregnancy.
If you’re pregnant or breastfeeding, it’s best to consult with a healthcare professional before eating rhubarb. They can provide personalized advice based on your individual needs and health status. In general, it’s recommended to limit your intake of rhubarb to small amounts and to avoid eating it if you have any underlying health conditions.
Can you eat rhubarb if you have digestive issues?
While rhubarb can be a nutritious and delicious addition to a healthy diet, it may not be suitable for everyone, particularly those with digestive issues. Rhubarb contains high levels of fiber and oxalic acid, which can exacerbate digestive issues such as irritable bowel syndrome (IBS), acid reflux, and stomach ulcers.
If you have digestive issues, it’s best to approach rhubarb with caution. Start by eating small amounts and monitor your body’s response. If you experience any adverse reactions, such as bloating, gas, or stomach pain, it’s best to avoid eating rhubarb altogether. Consider consulting with a healthcare professional or a registered dietitian to develop a personalized diet plan that meets your needs.
How can you minimize the risks associated with eating rhubarb?
To minimize the risks associated with eating rhubarb, it’s essential to follow proper food safety guidelines. Always wash your rhubarb thoroughly before eating it, and consider soaking it in a mixture of water and vinegar to remove any pesticide or heavy metal residues. Only eat the stalks of the rhubarb plant, as the leaves contain high levels of oxalic acid.
Additionally, consider growing your own rhubarb using organic gardening methods to minimize your exposure to pesticides and heavy metals. If you’re purchasing rhubarb from a store or farmer’s market, look for certified organic produce and choose stalks that are fresh and free of damage. By following these guidelines, you can enjoy rhubarb while minimizing the risks associated with eating it.
