Overview

Hemlock spruce is a plant. People use the needles and the oil distilled from the needles, branch tips, or branches of fresh fir shoots for medicine.

Hemlock spruce is used for coughs, the common cold, bronchitis, tuberculosis, fever, pain and swelling (inflammation) of the mouth and throat, muscle and nerve pain, and arthritis. It is also used to fight bacterial infections.

Some people apply hemlock spruce directly to the affected area for inflammation of the respiratory tract, arthritis pain, nerve pain, and for feelings of tension. It is also used topically to improve circulation and as a bath additive for people who are mentally ill.

Hemlock spruce is very similar sounding to water hemlock and European water hemlock, which are entirely different plants. Be careful not to confuse hemlock spruce with either form of water hemlock, because the water hemlocks are very toxic.
