Hi Chang and Welcome!
I did some hunting on my own with regards to the Pine needle Tea you mentioned. One thing that stood out to me is the HIGH content of Vitamin C, which was surprising.
In my internet travels I found the following:
Quote:What's so special about pine needles and water?
lemonFirst, the amount of vitamin C is reported to be five times the amount found in a lemon, which is 83.2 mg, according to NutritionData web site.[1] That means a cup of pine needles would yield more than 400 mg per cup of brew. Vitamin C is an antioxidant and an immune system booster. It also improves cardiovascular system functions, improves skin and eye health, which alone accounts for many of the positive results from using the tea, such as a cure for scurvy.
Second, pine needle tea is high in fat-soluble vitamin A, an antioxidant beta-carotene, which is needed for healthy vision (especially in low light situations), skin and hair regeneration, and red blood cell production! The vitamin A explains a few more of the nutrition and health claims, but certainly not all of them. There is more to the tea than just vitamins A and C. There are many components to consider with swallowing a cup of pine needle broth!
Scientists are exploring the health and nutrition claims for pine tree foods that have been consumed for hundreds of years, such as the needles, bark, nuts (seeds), pollen, and resin (sap). So far, they have found enough information to back up the medicinal claims with the potential for more uses. The following list is only a sampling of the research being examined.
Documents contained by the National Center for Biotechnology Information, U.S. National Library of Medicine, section PubMed.gov., pertaining to pine needle extract, or tea, and the research being done:
Chemical composition of essential oils from needles and twigs of balkan pine (Pinus peuce grisebach) grown in Northern Greece. An investigation finds many components in the oil extracted from twigs and needles.
Comparison of methods for proanthocyanidin extraction from pine (densiflora) needles and biological activities of the extract. Proanthocyanidins are flavonoids with fantastic properties: antioxidant, antidepressant, antibacterial, antiviral, antitumor, anti-inflammatory, immune system-boosting, cardiovascular-protecting, triglyceride-reducing, and more. This report may confirm all the claims that pine needle tea can help ease, if not cure, most anything.
Flavor compounds of pine sprout tea and pine needle tea. A report found 55 flavor compounds in pine sprout tea, and 29 flavor compounds in pine needle tea.
Plasma triglyceride-decreasing components of pine needles. Components extracted from pine needles using a vinegar solution are believed to reduce triglycerides.
Effect of new polyprenol drug ropren on anxiety-depressive-like behavior in rats with experimental Alzheimer disease. An extract from spruce and pine needles has potential as a treatment for depression, anxiety, and dementia.
Efficacy of anise oil, dwarf-pine oil, and chamomile oil against thymidine-kinase-positive and thymidine-kinase-negative herpesviruses. The three essential oils listed were highly effective against herpesviruses!
Antioxidant, antimutagenic, and antitumor effects of pine needles (Pinus desiflora) This study found that pine needle extract could potentially be used for cancer prevention!
