Is yerba mate elaborada con palo vegan?

Yerba mate elaborada con palo is a traditional South American tea made from the leaves and twigs of the yerba mate plant. The word "elaborada" means "elaborated" in Spanish, indicating that this yerba mate is carefully crafted using a specific process. The addition of "con palo" indicates that the tea includes the plant's stems, which can give the drink a slightly bitter taste and a slightly lower caffeine content compared to mate without stems. This ingredient is popular in Argentina, Uruguay, Paraguay, and southern Brazil, where it is often enjoyed with friends and family as a social drink, traditionally passed around in a gourd and sipped through a metal straw called a bombilla.
