West Indian elm

Guazuma ulmifolia

The Origins

It is widely found in areas such as the Caribbean, South America, Central America and Mexico serving several uses that vary from its value in carpentry to its utility in medicine.

 

Indigenous Knowledge

The seeds and fruit are gelatinous like chia. Soak a handful of west indian elm for a few hours, grind until liquefy, strain and drink. It is good for women’s relaxation and stress and for the health of ovaries and menstruation.

A decoction of bark and leaf is used for constipation and kidney disorders.

Biomedical Science

Guazuma ulmifolia Lam., more commonly known as West Indian elm or bay cedar, has shown great potential in clinical studies as an anti-diabetic therapy for people suffering from Type-II diabetes (T2-D) (Alonso-Castro et al. 2008). G. ulmifolia is especially of interest to researchers because while it does possess anti-diabetic properties, it does not seem to induce obesity, as many of its pharmaceutical counterparts are inclined to do (ibid.). Additionally, G. ulmifolia has exhibited antihypertensive, vasorelaxing, and antiobesity activity (Iswantini et al. 2011; Magos et al. 2008). All of these actions, along with G. ulmifolia’s high antioxidant potential (Feltrin et al 2012), make this plant a relevant therapeutic for many people struggling with diabetes and its associated comorbidities, such as weight gain and cardiovascular conditions.

One study found that when used in conjunction with the chemotherapeutic agent, Doxorubicin, aqueous extracts of the bark and leaf of G. ulmifolia reduced oxidative stress and exhibited cardioprotective activity without interfering with the agent’s chemotherapeutic activity. Therefore, G. ulmifolia may also be a potentially beneficial adjuvant therapy in cancer treatment (Dos Santos et al. 2018).

Eating large amounts of different parts of the plant can cause nausea, vomiting and diarrhea.

Note: West Indian elm bark has been documented in several animal studies to have uterine stimulant activity and it should not be taken during pregnancy.
