The Botanical Reality: Lemon Balm is Alkaline
Many people assume lemon balm (Melissa officinalis) is acidic due to its fragrant, lemony scent. However, this is a misnomer based on the aroma, not its botanical properties. Lemon balm is a perennial herb in the mint family, completely unrelated to the citrus fruits that share its scent. When prepared as a tea or consumed as an herb, it is definitively alkaline. A report by Kent Tea and Coffee Co indicated that lemon balm tea has a pH level of approximately 8.0 once digested, placing it firmly in the alkaline category. This contrasts sharply with actual lemon juice, which is highly acidic with a pH of about 2.0. The plant's alkaline nature is further supported by the fact that it thrives in slightly alkaline soils, tolerating a pH range of up to 7.6.
The Role of Chemical Components
While the overall herb is alkaline, it's important to understand its chemical makeup. Lemon balm contains several beneficial compounds, including phenolic acids, with rosmarinic acid being a major component. Some scientific studies, for instance, have examined the acidic fractions of lemon balm extracts. However, these concentrated extracts differ from the overall herb or typical tea preparation. The presence of these specific acidic compounds within the plant does not negate the overall alkaline nature of the herb when ingested as a whole leaf tea or culinary herb. The key takeaway is that the sum of the herb's components and their metabolic effects result in an alkaline product.
Why the Confusion with Lemons?
The primary source of confusion stems from the name and aroma. Lemons and their juice are well-known for their citric acid content, which makes them highly acidic to the taste and in their initial state. While the body metabolizes citric acid in a way that can have an alkalizing effect on the urine, this is a metabolic process entirely different from the inherent alkaline properties of lemon balm tea. The following table clarifies the significant differences between the two.
| Feature | Lemon Balm (Tea) | Lemon Juice (Citrus Fruit) |
|---|---|---|
| Botanical Family | Mint Family (Lamiaceae) | Citrus Family (Rutaceae) |
| pH Level (Prepared) | ~8.0 (Alkaline) | ~2.0 (Acidic) |
| Scent Source | Aromatic plant compounds like citronellal | Citric acid and other citrus compounds |
| Effect on the Body | Calming, antioxidant properties | Metabolic alkalizing effect after digestion |
| Primary Use | Herbal tea, calming agent, flavor | Culinary flavoring, drinks, acidic applications |
How to Enjoy the Alkaline Benefits of Lemon Balm
Incorporating lemon balm into your routine can be done easily, especially through herbal tea. By using the fresh or dried leaves, you can create a calming and naturally alkaline beverage. Here are some simple methods:
- Brew a Fresh Tea: Crush fresh lemon balm leaves to release their oils, then steep in hot (not boiling) water for 5-10 minutes. This provides a milder flavor and preserves the beneficial compounds.
- Use Dried Leaves: For a more concentrated flavor, use dried lemon balm leaves. Steep a teaspoon of dried herb per cup of hot water.
- Combine with Other Herbs: Lemon balm pairs well with other alkaline herbs like chamomile or mint for a custom blend. Ensure any additions are also alkaline if maintaining pH balance is your goal.
- Add to Salads or Dishes: Chop fresh lemon balm leaves and sprinkle them over salads, fruit desserts, or add to marinades for a delicate, non-acidic lemony flavor. This utilizes the herb in its whole, alkaline form.
Conclusion: No Cause for pH Concern
In conclusion, the question "Is lemon balm alkaline or acidic?" is settled by looking at its botany and common uses rather than its deceptive name. As a member of the mint family, lemon balm is inherently alkaline. Whether enjoyed as a calming herbal tea or used as a fresh culinary herb, it provides a gentle, non-acidic flavor profile. The presence of some acidic fractions within concentrated extracts is a nuance that doesn't define the overall nature of the whole herb. Therefore, individuals seeking to avoid acidic foods or beverages can confidently incorporate lemon balm into their diet without concern for its pH level.

The Difference in Extracts
It's worth noting that the process of creating concentrated extracts can change the chemical profile. An ethanolic extract of lemon balm can be separated into acidic and non-acidic fractions. In such studies, the researchers found that the acidic fraction exhibited potent protective effects. This highlights that while the whole plant and tea are alkaline, specific, highly processed applications can isolate particular components. For the average consumer using fresh or dried leaves, however, this distinction is not relevant to the final, ingested product's overall pH.
