Eucommia Bark Side Effects

If done with the proper amount of care and caution, the bark rarely leads to serious repercussions. However, an overdose can cause dizziness, drowsiness, spasms, fatigue, palpitations, and comas in the most severe cases. It can also cause allergic reactions, and though such reactions to Eucommia bark are rare, it is important to keep in mind that they could, nevertheless, be induced due to the latex properties of the Eucommia bark.

Latex is a famous contact allergen, meaning that skin exposure to it can cause or trigger an allergy. Latex is used in the production industry (i.e., workers who frequently use latex gloves), and so the reaction could be due to cross-sensitivity rather than to the actual natural substance. Many people who react strongly to latex-allergy inducing plants and substances can and do consume the herbs with the same ingredients, and experience no severe side effects.
