Navigating a Low-Oxalate Diet with Herbal Teas
For many, a cup of tea is a daily ritual. However, for individuals needing to reduce their oxalate intake—often to prevent the formation of calcium oxalate kidney stones—the choice of tea becomes important. Oxalates are naturally occurring compounds found in many plants, and while most people can consume them without issue, some sensitive individuals need to be cautious. Herbal teas, or tisanes, offer a great alternative to true teas (black, green, oolong) which are made from the Camellia sinensis plant and generally contain higher oxalate levels.
The Best Low-Oxalate Herbal Tea Choices
Choosing the right herbal tea is a simple and effective way to manage your oxalate consumption. The following herbal options are known for having very low to undetectable oxalate content, making them excellent additions to a low-oxalate diet:
- Rooibos Tea: Made from the leaves of the South African 'red bush,' rooibos is naturally low in oxalates. It has a slightly sweet, earthy flavor and is rich in antioxidants. Both red and green rooibos are safe choices.
- Peppermint Tea: This refreshing, caffeine-free brew is a popular choice for digestion and is also reliably low in oxalates.
- Chamomile Tea: Known for its calming properties, chamomile tea is made from chamomile flowers and contains very minimal amounts of oxalate, making it a soothing and safe drink.
- Ginger Tea: While ginger supplements may contain more concentrated oxalates, using fresh ginger root for a homemade tea provides a low-oxalate, anti-inflammatory beverage.
- Ginseng Tea: Research has shown that ginseng tea has undetectable levels of oxalate, making it one of the safest options available.
- Fruit Teas: Many fruit-based herbal teas are low in oxalates, but it's important to be mindful of ingredients. Opt for blends made from low-oxalate fruits like peaches, apples, and cherries. Avoid high-oxalate fruits like berries, black currants, and rhubarb.
- Hibiscus Tea: While containing a slightly higher amount of oxalate than some other herbals, studies suggest hibiscus tea may help decrease oxalate retention in the body. For most on a low-oxalate diet, it is considered safe in moderation.
What to Avoid: High-Oxalate Teas and Add-Ins
Conversely, some teas should be limited or avoided. Black tea, for example, is significantly higher in oxalates than herbal alternatives. Other teas to be cautious of include:
- Matcha: Because you consume the whole, ground leaf, matcha contains a much more concentrated amount of oxalates and should be avoided.
- Chocolate or Cocoa Mixes: Many beverages containing chocolate are high in oxalates.
Furthermore, what you add to your tea can also impact your oxalate load. While milk can help bind oxalates in black tea, adding high-oxalate ingredients to any tea should be done cautiously. This includes almond milk, soy milk, and high-oxalate sweeteners.

Preparing Your Low-Oxalate Tea
For the lowest possible oxalate content, consider these preparation tips:
- Use fresh herbs: Brewing with fresh, low-oxalate herbs or roots can be more reliable than using pre-packaged blends, which may contain unlisted high-oxalate ingredients.
- Shorten the steep time: For any tea, a shorter infusion time can reduce the amount of soluble oxalates that leach into your cup.
- Dilute with water: Simply drinking more water throughout the day is a primary recommendation for preventing kidney stones. You can also dilute your tea to further reduce oxalate concentration.
- Stay hydrated: Overall fluid intake is crucial for diluting urine and preventing mineral concentration, regardless of oxalate content.
Conclusion
Maintaining a low-oxalate diet does not mean sacrificing the pleasure of a warm cup of tea.
