“During the Spanish Flu, those who ate pine needles didn’t get sick.” I came across this in one of my notebooks recently. I had jotted it down several months ago when I watched a webinar on herbal remedies. Unfortunately, I’d failed to record my source, but the webinar had touted the benefits of various parts of the pine tree. As I recall, the 1918 patients were being treated with pine needles for scurvy.
I already knew pine trees are edible, if rather hard to chew. Years earlier, I had read one of Euell Gibbons’ books in which he queried, “Did you ever eat a pine tree?” Then he proceeded to tell how to prepare and dine on the various parts.
More recently, I bought a book at a Garden Club event, I Eat Weeds by Priscilla G. Bowers. She devotes 68 pages to wild edible plants and the rest of the book to recipes. I’ve tied many of them and one of my favorites is Pine Needle Tea. I have pine trees on my property and occasionally a storm will blow down a few branches. I’ll salvage a generous handful and make tea. You can drink it hot or iced. It’s delicious, but I didn’t know it could protect you from the Spanish flu. I needed more information.

Iced Pine Tea with Mint
I Googled “pine needles/Spanish flu” hoping to find my source. I couldn’t, nor could I find any evidence of pine being used as a treatment during the 1918 pandemic. However, I did find information on pine in regards to modern influenzas.
Pine is rich in vitamins C and A, but it is also rich in shikimic acid, which is an ingredient in Tamiflu (Oseltamivir)! This ingredient is imported from China where it’s extracted from the star anise tree, but we grow our own source of shikimic acid right here in the US. You may have it growing in your backyard.
I found two newspaper articles on the subject, from the Bangor Daily News in Maine and the Pocono Record in Pennsylvania. Both discussed how timber companies could gather pine needles from harvested trees and extract shikimic acid to supply pharmaceutical companies.
In 2006, CNN.com published an article about a Canadian company, Biolyse, that collects discarded Christmas trees to extract shikimic acid. Chemist Brigitte Kiecken, CEO of Biolyse, expressed concern about the inevitability of a viral pandemic. “It’s an urgent matter, and we should be starting production—not once the pandemic hits, but before that. On a personal level, I’m scared, and on a professional level, I’m terribly frustrated,” she said. “Government and industry have to work together now. We’ve been warned for ample time, and it [a pandemic] is bound to happen.”
This was 14 years ago! Yikes!
I wondered, if pine can protect you from the flu, what about Covid 19? I kept digging and was surprised by the research that’s been done on the medical uses of pine.
There are 80 to 90 species of pine around the world, and most are edible. In fact, other conifers are also edible. That includes trees such as fir, spruce, larch, cedar, and hemlock. This is not the hemlock that killed Socrates. Poison hemlock is a member of the carrot family. Beware of wild carrots. Also beware of these poisonous trees: ponderosa pine, yew, and Norfolk or Australian pine. And remember, not all evergreens are conifers.
Another caution: pregnant women and those who could become pregnant should not drink pine needle tea as it could cause abortion.
Besides Vitamins A and C and shikimic acid, pine contains protein, fat, phosphorus, iron, and a long list of other compounds. The composition of nutrients varies with the species and season, which is why you won’t see a Nutrition Facts chart attached to your pine tree. Oils from pine needles could potentially treat heart disease, diabetes, senile dementia, and hypertension. And the list goes on: obesity, depression, and anxiety. Pine is anti-microbial and boosts your immune system, so it’s good for colds, sore throat, sinus and chest congestion. To relieve upper respiratory illness, you can inhale the vapor.
But what about our current scourge? Doctors are scrambling to find treatments for Covid. Maybe all they need to do is look out the window. If pine indeed worked during the pandemic 100 years ago and contains an ingredient used today to treat influenza, would it be effective for coronavirus?
To my knowledge, no studies have been done yet on pine and Covid 19, but there have been studies involving other coronaviruses, including SARS, which reared its ugly head in 2003, so it makes sense it would be good for Covid 19, too.
Priscilla Bowers’ recipe for Pine Needle Tea is simple:
Green pine needles, cut into 3” or 4” lengths
Water to cover
Sugar to taste
Bring to a boil in a sauce pan and hold 5 minutes, then let steep for 10. Strain and sweeten. Including some of the stems gives it more flavor.
I like to make it by the half-gallon and serve it iced. I take a generous handful of pine needles and twigs, cover them with water, bring it to a boil, simmer five minutes, then let it cool before I sweeten and dilute it. You may not need to sweeten the tea, depending on your taste. Honey will make it more healthful. Warning: pine rosin will stick to the pan. Use an old pan or one that’s easy to clean.
A windstorm last week blew down several pine branches. I gathered twigs, cut them into useable lengths, and put portion amounts into freezer bags. Now I have a supply to last me until the next windstorm.
Of course, I’m no doctor and can’t guarantee that Pine Tea will protect you from or cure Covid 19, but when you have something that won’t hurt you, is pleasant to drink, and might help, why not try it?
