Pine needle (Pinus radiata) is used in traditional folk remedies to treat a range of maladies including fatigue, depression, anxiety and sleep disturbance, along with diseases of the liver, nervous system, circulation, and skin. Pine needles are a good source of vitamin C, along with terpenes, flavonoids, phenolic compounds, and proteases with fibinolytic activity. Pine needle preparations may lower plasma cholesterol, reduce obesity and remove blood clots, and are a rich source of shikimic acid, which is used to manufacture the antiviral medication oseltamivir (Tamiflu®) and may neutralize the damaging effects of spike protein and counteract blood clot formation.
