What are the main drawbacks of Althaea officinalis?

•Last Updated: October 25, 2023

No toxicity has been identified in animal studies^[1] and no serious side effects have been reported in clinical studies.^[2]^[3]^[4]^[5] Therefore, extracts from Althaea officinalis appear safe to consume. However, the main drawback of Althaea officinalis is that there is insufficient evidence in humans to support the numerous health claims derived from the results of cell culture (in vitro) experiments and animal studies.
