Eastern hemlock (Tsuga canadensis) has a history of traditional use by some Indigenous peoples and early settlers in North America. The bark and leaves were sometimes prepared as poultices or teas and applied to wounds or used for their purported astringent and antiseptic properties. These practices were based on empirical use rather than scientific validation, often stemming from the plant’s tannin content, which can have mild astringent effects that may help reduce local inflammation or bleeding.

However, there is little to no robust scientific evidence supporting the efficacy of Eastern hemlock for treating injuries. Most references to its use are anecdotal or found in ethnobotanical accounts, not in clinical studies or pharmacological research. Furthermore, the modern medical literature does not recognize Eastern hemlock as a standard treatment for injuries, and its use is largely historical. It is important not to confuse Eastern hemlock (Tsuga canadensis) with the highly toxic poison hemlock (Conium maculatum), which is unrelated.

In summary, while there is a tradition of using Eastern hemlock in folk medicine for minor injuries, the evidence supporting its efficacy is weak and not scientifically validated. Its use today is rare and not recommended due to the lack of substantial evidence and the availability of safer, proven treatments.
