What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each drug listed above links to the full report for that exact Oswego Tea combination — clinical detail, likelihood, evidence level, and citations.

Overview

Oswego Tea is a traditional herbal tea made from Monarda didyma, a flowering plant in the mint family that is also commonly called bee balm, scarlet bee balm, or red bergamot. It is native to eastern North America and is known for its bright red flowers and minty, fragrant leaves.

The name "Oswego Tea" comes from the Oswego people, a Native American group near present-day New York, who reportedly used the plant to make a tea. Early American colonists are said to have brewed it as a substitute for black tea. Today people grow the plant in gardens both for its beauty and to make a flavorful herbal tea.

The tea is mainly enjoyed as a pleasant beverage, but it has also been used in folk medicine for digestion, colds, and minor ailments.

How it works

Like other mint-family plants, Monarda didyma contains aromatic essential oils. One notable compound is thymol, which is also found in thyme and has known antiseptic properties in laboratory settings. The plant also contains other volatile oils and antioxidant plant compounds.

These compounds are the likely reason the plant has a strong scent and a history of use for colds, sore throats, and minor infections. However, most evidence for these effects comes from laboratory or animal research on plant extracts or essential oils, not from studies of the brewed tea in people.

In short, the proposed mechanisms are reasonable based on the plant's chemistry, but they have not been confirmed to work in the human body when the tea is consumed.

Safety & precautions

As an occasional herbal beverage made from the leaves and flowers, Oswego Tea is generally considered low-risk for most healthy adults. However, its safety as a stronger medicinal preparation or supplement has not been well studied.

People who are allergic to plants in the mint family may react to it. Start with a small amount the first time to see how you tolerate it.

Pregnancy and breastfeeding: There is not enough reliable safety information for these situations. To be safe, pregnant people should avoid medicinal amounts, and those who are breastfeeding should use caution or avoid it. Always check with your doctor or pharmacist first.

If you have a chronic medical condition, take prescription medicines, or plan to give it to a child, talk to a healthcare professional before using it.

Side effects

Oswego Tea is not known to cause serious side effects when used as a normal beverage. As with many herbal teas, possible mild effects could include stomach upset or an allergic reaction, especially in people sensitive to mint-family plants.

Concentrated essential oils from Monarda are much stronger than the tea and should not be swallowed unless directed by a qualified professional, as essential oils can be irritating or toxic if misused.

Stop using it and seek medical care if you notice signs of an allergic reaction such as rash, itching, swelling, or trouble breathing.

Dosing

There is no established standardized dose for Oswego Tea. It is traditionally prepared by steeping a small handful of dried or fresh leaves and flowers in hot water for several minutes, then straining.

If you buy a packaged product, follow the directions on the label. Because formulations and strengths vary, and because research is limited, it is wise to start with a small amount and check with your pharmacist or doctor before using it regularly or in larger amounts.
