Contraindications:
- Animal studies have demonstrated the hypotensive properties of erva tostão. This plant is probably contraindicated for persons with low blood pressure.
- This herb has also demonstrated myocardial depressant activity and should therefore not be taken by anyone with heart failure or those taking heart depressant medications unless under the direction and care of a qualified health care practitioner.
Drug Interactions: Erva tostão may enhance the actions of cardiac depressant medications. In an animal study erva tostão inhibited barbiturates and decreased sleeping time. Therefore, the use of this plant may decrease the effect of barbiturates.
