Quick Summary

Costmary (Tanacetum balsamita) is a medicinal plant belonging to the Tanacetum genus, traditionally used for various health purposes. Some scientific studies have explored its phytochemical profile and potential health benefits, but clinical evidence remains limited. The safety profile and possible drug interactions of Costmary have not been well established.

What is it?

Costmary, also known as Bible leaf or alecost, is a perennial herb in the Asteraceae family. It is native to Europe and has been used historically in traditional medicine and as a culinary herb. The plant is characterized by fragrant leaves and yellow flowers and belongs to the same genus as other medicinally studied plants like Tanacetum vulgare.

Traditional Uses

  • Traditionally employed for digestive complaints, particularly dyspepsia symptoms such as bloating and nausea.
  • Used topically for festering wounds, skin ulcers, urinary tract infections, and sexually transmitted diseases, often referenced in related Tanacetum species.

Active Compounds

Phytochemical studies on Tanacetum species indicate the presence of metabolites with potential biological activity, including essential oils and flavonoids. However, specific compounds from Costmary have been insufficiently characterized, and their pharmacological roles require further research.

Potential Benefits with Evidence Levels

  • Traditional Use: May help with digestive issues like indigestion and nausea based on historical use.
  • Preclinical Evidence: In vitro studies of Tanacetum species suggest antimicrobial, antioxidant, hepatoprotective, and possible hypotensive, neuroprotective, anticancer, and anti-inflammatory properties. Some metabolites show biological activity, but data on Costmary are limited.
  • Clinical Evidence: No randomized controlled trials or systematic reviews specifically on Tanacetum balsamita were found to confirm efficacy or safety in humans.

Side Effects

There are no well-documented adverse effects from clinical trials or systematic reviews on Costmary. Some related species and their essential oils may pose risks, but these findings do not necessarily apply to Costmary.

Drug Interactions

No documented studies or evidence exist regarding drug interactions with Costmary.

Who Should Avoid It

Due to the lack of clinical safety data, use of Costmary is not recommended during pregnancy or breastfeeding without medical advice. Individuals should exercise caution if considering use and consult healthcare providers, especially if taking medications or managing health conditions.

Evidence Limitations

  • Most evidence comes from in vitro or animal research and traditional use reports, without rigorous clinical validation.
  • Randomized controlled trials or meta-analyses evaluating efficacy and safety in humans are absent.
  • Phytochemical and pharmacological profiles need deeper clinical investigation to substantiate traditional claims and ensure safety.
  • Lack of data on appropriate dosing, preparation methods, and standardization limits clinical guidance.
