Carphephorus odoratissimus

Carphephorus odoratissimus, also known as vanillaleaf or Deer Tongue, is a herbaceous plant from the family of the composites (Asteraceae). It is native above all to the southeastern United States, where it grows in moist meadows and open woodland areas. The plant is known for its characteristic vanilla-like scent, which is attributable to the coumarin derivative contained in its leaves. Besides its traditional use as a flavoring and tobacco additive, Carphephorus odoratissimus is also valued in naturopathy.

What benefits does Carphephorus odoratissimus bring?

Because of its properties, the plant is highly valued in traditional medicine, where various effects are attributed to it. The body of studies on Carphephorus odoratissimus is not very meaningful, so that the properties ascribed to it in folk medicine are not verifiable. Therefore the following points are merely areas of application in traditional medicine and no factual, substantiated statements.

  • Anti-inflammatory action: In traditional medicine the plant is used for the treatment of inflammations and skin irritations. It is said to help reduce swelling and promote healing.
  • Calming and relaxing action: The vanilla-like scent of the plant is often used for aromatherapy in order to reduce stress and achieve a calming effect.

Unfortunately, not much is known about the mode of action of the plant either and the body of studies is very thin, so that no verifiable statements can be made

Side effects and risks

Although little can be said about the actual effect of Carphephorus odoratissimus, there are nevertheless a few points to observe when handling the plant:

  • Skin irritations: Direct contact with the leaves can provoke skin irritations in sensitive people.
  • Liver toxicity with excessive consumption: Coumarins can potentially be toxic for the liver in high doses.
  • Interactions with medications: Because of the coumarins it contains, the plant can have an anticoagulant effect, which is why people who take blood thinners should be careful.

Conclusion

Carphephorus odoratissimus is an interesting plant with versatile areas of application in naturopathy and aromatherapy. The potential of the plant needs to be explored further in research, and it remains to be seen whether the effects ascribed to it in traditional medicine can be demonstrated.
