What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • Pine needle tea is very popular in Japan, Russia, Korea and China. Around the world, healers have used pine needles, bark, resin, cones and seeds for:

    • Coughs, colds and flu
    • Skin infections and wounds
    • Inflammation
    • Diabetes

    The Algonquin people have used white pine needle tea to strengthen the immune system. In Latin America, especially Mexico, pine is important in folk medicine.[2]

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • In lab tests, pine needle extracts and essential oils have shown antioxidant activity, killed some bacteria and fungi, and may help reduce inflammation. Scots pine needle extract slowed the growth of some breast cancer cells. The review found a large gap between traditional uses and scientific testing.[2]

In short
