About the Pine Tree

The mighty pine tree is one of the most common trees on earth — making up close to 1% of the plant population of earth. They can be found thriving in both the coldest, and hottest environments on the planet.

All parts of the pine tree are used medicinally, and the wood is an importance source of lumbar for construction.

The leaves (needles) are an excellent source of vitamin A and C, the resin is a powerful antibacterial and carminative agent, the bark and pine nuts are highly nutritive, and the pollen is used as an analgesic, male tonic, and longevity-enhancement agent.

The pine tree is, and always has been an invaluable ally to humans.

What Are Pine Trees Used For?

There are so many uses for the pine tree, it’s hard to list them all. The bark, needles, seeds, and pollen are incredibly nutritious, and the resin contains powerful antimicrobial and vulnerary compounds.

Humans have been using the pine tree as food and medicine for thousands of years in almost every Northern culture on earth. Many of the traditional medical uses for pine trees still stand today — but have become less popular over other more exotic herbs.

A common theme with herbal medicine is that it’s usually the least interesting, most common plant species that have the most to offer. Yet we’re always looking for that new exotic herb or supplement to use instead.

The most popular use of the pine tree today is in the form of topical salves made from the resin and male tonic supplements made from the pine pollen. Pine nuts are also a common source of nutrition you can pick up at any grocery store.

The needles and bark are also exceptionally nutritious and can be made into a tea or decoction (respectively) to support general health, as well as treating debility, fatigue, and nutritional deficiencies.

+ Pine Needle Uses

Pine needles make for an excellent tea. They're rich in vitamin A, Vitamin C, and a host of medicinal essential oils.

Pine needle tea is great for supporting the immune system, releasing phlegm from the lungs, easing a sore throat, curbing gas and bloating, or warming up on a cold winter hike.

An infusion of the needles can also be applied topically to the skin as an antimicrobial and vulnerary.

Fresh needles collected in the spring can be eaten raw and add a pleasant "piney" or "rosemary" flavor to the dish. You can also infuse these fresh pine sprigs with honey or butter.

A tincture can be made from the needles using a high alcohol menstrum (at least 95%). Use, sparingly.

+ Pine Resin Uses

Pine resin seeps out of cuts and scratches of the tree — it's used to seal the wounds and prevent infection. As a result, it's no surprise this pine resin has exceptional antimicrobial properties. It's insecticidal, anti-fungal, and antibacterial.

The resin makes for an excellent addition to topical salves designed to speed wound healing.

You can also make or buy tinctures of pine resin using a high-proof alcohol as the solvent. These are useful for releasing phlegm from the lungs and eliminating gas and bloating from the digestive tract. However, use it sparingly as the resin can be irritating to the GI tract in high amounts.

+ Pine Pollen Uses

Pine pollen has a long history of use in Asia for promoting strength and male virulity. High-proof extracts of the pollen are used by older men to maintain testosterone levels. There's a lot of promise for this effect in the scientific literature (more on this later) — but it's important to note that pine pollen is not an anabolic steroid and can't be used to boost testosterone in younger men. It only appears to work if testosterone levels are low to begin with.

Outside male virility, pine pollen is an excellent nutritional supplement for men and women alike. It's rich in the amino acids, minerals, and vitamins required for optimal health.

+ Pine Bark Uses

Pine bark is rich in vitamin C and A and a few unique medicinal components. The bark can be decocted to make a strong bitter tea with a host of medicinal benefits. Some herbalists use the bark for heart disease, varicose veins, clotting disorders, and cancer.

+ Pine Nut Uses

Pine nuts, like the rest of the pine tree, are very nutritious. They're rich in vitamins B1, B2, B6, E, C, D2, D3, and A.

Pine nuts are also rich in nicotinamide, folic acid, B-carotin, potassium, sodium, calcium, magnesium, phosphorus, iron, manganese, copper, zinc, and selenium — to name a few.

 

Traditional Uses of Pine Trees

Anybody living in proximity to these common forest plants (especially in Northern climates) have developed a set of uses for the herb — many of which are the same all over the world.

The pine tree has been used for coughs, allergies, urinary tract infections, sinus infections, skin infections, debility, joint pain, inflammatory diseases, immune deficiencies, scurvy, and much more.

Native American tribes used the pine tree as an important source of nutrition during the winter months — consuming the nuts, bark, and needles of the pine tree.

Early explorers to reach North America from Europe eventually started using pine needle tea to ward off scurvy.

There are countless uses for this impressive tree as well when you consider its nutritive benefits. Almost any medical condition can stand to benefit from optimal nutrition, which explains why the tree has been used in traditional medicines for almost any cause of debility.

The resin was also considered a valuable ingredient in topical salves for skin conditions, infections, and insect bites.

The boughs of the pine tree were used as an insect-repellant bedding to eliminate common pests like bedbugs or fleas.

Botanical Information

The Pinus genus consist of roughly 144 different species of coniferous trees. It’s one of the oldest plants on earth — dating back at least 200 million years.

Pine trees are incredibly common, they’re found on every continent, and dominate forests in the Norther hemisphere. One report suggests the humble pine tree makes up about 1% of the entire plant population of earth.

No matter where you go in the northern Hemisphere, you’re likely to find pine trees a permanent member of the landscape. However, if you look more closely, different regions are home to a specific species of pine tree.

 

Harvesting & Preparation

All parts of the pine tree can be used medicinally. The leaves make a nutritious tea, the bark can be decocted into a strong tea, the resin can be made into antimicrobial salves, and the pollen can be supplemented as a male tonic.

Different parts of the tree should be harvested in different seasons:

  1. Pine Pollen — the pine tree only releases its pollen in the early spring or summer. Each tree releases an ton of it. Collect it by placing bags over the catkins and giving it a shake.

  2. Pine Needles — these can be harvested anytime, but spring is the best in order to get the young growth. Newer growth has a much better taste and higher terpene concentrations.

  3. Pine pitch (resin) — This part can be harvested all year. I like to harvest it in the winter when it’s extra hard as I find this easier to collect in chunks rather than making a sticky mess of evertthing when the resin is still gooey.

  4. Pine Bark — You can collect this part of the tree anytime of the year. I find it best in the spring, summer.

Pharmacology & Medical Research

+ Antinociceptive (Pain-Reduction)

In animal studies, an ethanol extract of pine pollen (100 and 200 mg/kg orally) produced significant inhibition of both pain transmission and inflammation compared to the control group [1]. (Species tested (Pinus densiflora).

+ Anticholesterolaemic

The needles of pine trees (Pinus morrisonicola) has been shown to inhibit copper-induced low-denisty lipoproteins (LDL) oxidation [2]. The study involved four different solvent extracts, but the ethyl acetate extract showed the greatest antioxidant activity overall.

+ Anti-Inflammatory

Several studies have shown different parts of the pine tree to have anti-inflammatory effects on various inflammatory enzymes and messenger molecules.

The needles were shown to possess COX-2 inhibitory activities in animal models [2].

+ Longevity

One of the longest-running applications of the pine pollen — dating back thousands of years in China — was for promoting long-life. This was especially true in men, where the pollen was used to delay the effects of aging, and sustain male virility long into old age. In traditional Chinese medicine, pine pollen is considered a jing tonic. Jing is a term used to describe “life essence” — it’s essentially our virility. When jing runs out, we die. Chinese medicine considers pine pollen a tonic for the lungs, kidneys, heart, spleen, and liver — all five major organs in the Chinese medical system.

The modern term for this effect is an adaptogen — something that improves our ability to resist both internal and external stresses and maintain homeostasis (balance).

In order to offer such broad benefits to the body, pine pollen must act on a central regulatory system. Some herbs, such as ginseng do this by acting on the hypothalamus — which is the region in the brain that manages homeostasis within the body. Other herbs, like cannabis achieve this by boosting the effects of a regulatory system called the endocannabinoid system.

A study published in 2012 looked at the potential anti-aging effects of pine pollen [3]. The study injected mice with D-galactose — which is a compound used to induce premature aging by increasing the formation of advanced glycation end-products (AGEs). Pine pollen extract was found to hinder the production of AGE at doses between 500 and 1500 mg/kg. This effect was noted to be comparable in effects to 100mg/kg aminoguanidine — a well-known longevity-enhancement medication through AGE pathways.

+ Testosterone

There was a study published in 2013 that showed black pine tree pollen (Pinus nigra) contained epi-testosterone, as well as a handful of other androgenic compounds (5α-androstane-3α,17β-diol, 5β-androstane-3α,17β-diol and etiocholanolone) [1]. The problem is that the testosterone levels contained in pine pollen were so insignificant it was unrealistic to expect any change in testosterone levels for those taking the supplement. It’s estimated that 10 grams of pine pollen contains about 0.8 micrograms of testosterone [4].

To put this in perspective, the usual dose of injectable testosterone is over 100 mg. This is an injectable form of testosterone too — which has 100% absorption rate. Oral ingestion of testosterone has significantly less absorption — closer to 3 –7%.

While you can’t use pine pollen as a natural source of testosterone, it does offer improvements to testosterone levels in older men through alternate mechanisms.

The improvement in male health and libido after using pine pollen is most likely a combination of its potent nutritional profile and anti-inflammatory benefits. Pine pollen is particularly rich in amino acids like nicotinic acid and pantothenic acid — both of which have been shown to play a major role in the function of the testes where testosterone is produced.

The benefits of pine pollen on testosterone levels are most notable in older men experiencing the natural drop-off of testosterone levels. There’s no evidence to suggest pine pollen can boost testosterone levels in healthy, younger men.

 

Phytochemistry

The entire pine tree is a rich source of nutrition. The bark, leaves, and pollen are all high in vitamins and minerals, while the resin is particularly rich in terpenes and other volatile compounds.

+ Pine Pollen Constituents:

Amino acids, riboflavin, nicotinic acid, pantothenic acid, pyridoxine, biotin, inositol, folic acid, vitamin D2, vitamin D3. Some species (Scot’s pine — Pinus sylvestrus) has been found to contain testosterone, epitestosterone, and androstenedione — however, the concentrations are too low to reasonably offer any direct benefits through supplementation. The male tonic effects of pine pollen are primarily the result of other compounds, rather than from the androgens themselves.

+ Pine Resin Constituents

Abietic acid, dehydroabietic acid, elliotic acid, isopimaric acid, levopimaric acid, palustric acid, pimaric acid, sandaracopimaric acid, strobinic acid, volatile oils.

+ Pine Needle Constituents

Leucocyanidin, neoabietinic acid, pinosylvin monomethyl ester, strobic acid, antioxidants, volatile oils including α-terpineol (30.2%), linalool (24.47%), limonene (17.01%), anethole (14.57%), caryophyllene (3.14%), and eugenol (2.14%).

+ Pine Bark Constituents

Abietic acid, cis-abienol, leucocyanidin, neoabietinic acid, pinosylvin, monomethyl ester, strobic acid, volatile oils.

 

Cautions & Safety Information:

All pine species are considered safe. There is one species of tree that resembles the pine tree — the yew tree — which is toxic. The yew tree can be differentiated by the smaller, flat needles and little red berries.

The pollen of the pine tree is a common cause for allergy — take with caution when using pine pollen for the first time to ensure there are no allergic reactions.

Be careful when using tinctures of the pine resin to avoid causing gastrointestinal irritation. Start with a very low dose before increasing gradually once you get a feel for how it affects you directly.

Horopito (Pseudowintera colorata)

horopito.jpg

What is Horopito?

Horopito is commonly known as New Zealand pepperwood for its mild spicy flavor and exclusivity to the cooler islands of the south pacific ocean — including New Zealand.

This herb has a lot of traditional uses as medicine but went largely noticed by the international herbal medicine community. Recently there’s been a surge in interest in the plant after a series of studies were done to assess the medical value of traditional New Zealand herbs.

Horopito is used for skin and digestive conditions largely due to the plant’s potent antifungal actions. This plant has been shown to kill candida, as well as a number of parasitic worms.

The mild spicy nature of the plant also brings some circulatory stimulant and analgesic activity.

This plant has a lot of practical applications, especially for infectious fungal or parasitic conditions. It’s likely this plant will become much more commonplace in western herbal medicine within the next 5 to 10 years.

 

What is Horopito Used For?

The primary uses of horopito in modern herbal medicine is for fungal, bacterial, and parasitic infections.

A liquid extract of the herb is the most common form used today, but you can also find capsules and topical applications of the herb. For skin infections, such as ringworm or eczema, a poultice of the leaves can be applied directly, but a liniment is more common as the plant can be difficult to grow outside New Zealand.

 

Traditional Uses of Horopito

The Maori of New Zealand have been using horopito for a long time and have a long list of applications for its leaves.

The Maori use horopito in the following ways:

  • As a flavoring agent (spicy flavor profile)

  • For sexually transmitted infection

  • Ringworm

  • Chaffed or damaged skin

When the early Europeans colonized New Zealand many of them began using the herb as a source of vitamin C to prevent or treat scurvy.

Manuka (Leptospermum scoparium)

manuka-Leptospermum-scoparium-cover.jpg

What is Manuka?

In New Zealand, where manuka trees grow, the Maori consider male tea tree plants "Kanuka" and the female plants "Manuka". The plant is regarded very highly in this culture as a medicinal species.

The most well-known form of manuka is in manuka honey. This is a honey made by bees feasting primarily on manuka bushes. The honey has an impressive antibacterial profile when made from these plants. This is also reflected in the herb itself, which has been shown to have potent antibacterial, anti-fungal, and antiviral activity.

Most of the medicinal benefits of the plant come from its essential oil content, which can vary a lot depending on the region the plant was grown in.

 

What is Manuka Used For?

Internally, manuka is used to treat gastrointestinal conditions like diarrhea, colic, inflammatory bowel syndrome, and dysentery. It's also used for urinary tract infection, anxiety, and cold/flu infections.

Manuka is used topically for its antibacterial, and vulnerary actions. It's used to treat slow healing skin and bone injuries, bacterial infections, candida, and eczema. It can be gargled for gingivitis, or for general oral hygiene.

Manuka honey is another common form of the plant. It's become so popular worldwide, it's been standardised by the phenol content. This is expressed as a unique manuka factor (UMF) value set by the Active Manuka Honey Association (AMHA). Anything over UMF 5 is considered strong enough to kill MRSA.

Mullein (Verbascum thapsus)

mullein-verbascum-thapsus-cover.jpg

Mullein

Mullein is considered a staple in herbal medicine. It wasn't native to North America and was brought over by European settlers. Despite the new introduction of the herb, it was quickly adopted into use by the local native Americans and is even referred to commonly as Indian Tobacco.

Mullein is a very safe herb and offers benefits to a number of different systems in the body.

Out of all systems, mullein is most commonly used for respiratory and digestive system conditions. It's popular as an anti-catarrhal and for both soothing dry coughs, and eliminating catarrh with productive coughs. Although the entire plant can be used for either one, the leaves are generally preferred for dry coughs and the roots for productive coughs.

Mullein is as useful topically as it is internally for inflammation, muscle spasms, and infection.

 

What Is Mullein Used For?

Mullein is mainly used for treating respiratory infections and persistent coughs. Somewhat ironically, it's often smoked for its soothing effect on the lungs. It tends to increase moisture in the lungs, especially the leaves, making it especially useful for unproductive, dry coughs.

It's also used for gastrointestinal inflammation, parasitic infection, and muscle aches. It tends to have a humidifying effect throughout the body, providing a soothing effect, especially with dryness.

One of the most well-known uses for the herb is in the form of an infused oil for ear infections.

 

Herb Details: Mullein

Botanical Information

Mullein belongs to the figwort family (Scrophulariaceae) — a family consisting or roughly 65 different genera and 1800 species.

The Verbascum genus itself contains around 250 different species.

Verbascum is a popular garden plant for its ability to thrive in dry, nutrient-poor soils, and for their incredibly long flower duration.

The herb is biennial — the first season growing in a rosette leaf pattern, the second with a large velvety flower spike. Some mullein plants can grow up to three meters tall.

 

Clinical Applications Of Mullein:

Although there are many ways to use mullein, it excels with treating respiratory tract conditions. The leaves are excellent for treating dry coughs, while the root is much better for productive wet coughs.

Mullein is useful as a topical treatment for skin irritations, and as an oil for ear infections, especially the more drying flower of the plant.

Mullein also makes for an excellent lymphatic, both internally and externally.

 

Cautions:

Caution advised when working with the fresh leaf of this plant, as it can cause contact dermatitis in some individuals.

Gymnema (Gymnema sylvestre)

gymnema.jpg

What is Gymnema?

Gymnema is known as "the sugar destroyer" because of its unique ability to inhibit our ability to taste sweet foods.

This quality is used to combat sugar cravings in diabetics to control blood sugar levels.

It's been used for thousands of years in India for treating conditions involving "sweet urine." This is a common symptom of diabetes as sugar diffuses into the urinary tract. Old methods of diagnosis involved tasting the urine to identify a sweet taste.

Gymnema offers a variety of unique benefits towards conditions like diabetes, including changes to the pancreatic beta-cells, responsible for releasing insulin into the blood.

Gymnema is also a diuretic, helping to clear glucose from the blood through urine (in combination with plenty of water of course).

Finally, gymnema leaves inhibit the sweet sensation on the taste buds, making food taste bland and dull, which can be used to reduce the cravings for sweet (high sugar) foods responsible for maintaining the pathophysiology of diabetes and metabolic syndromes.

 

What is Gymnema Used For?

Gymnema is mainly used to treat metabolic conditions like diabetes, PCOS, and metabolic syndrome. It's also used for dental carries, and poor digestion.

+ Mechanisms

  • Inreases the number of insulin-secreting beta cells in the pancreas
  • Decreases the perception of sweet taste on the taste buds
  • Inhibits peripheral utilization of glucose by somatotrophin and corticotrophin.

Botanical Information

Gymnema is a member of the Apocynaceae (dogbane) family of plants.

In the past, gymnema was included in the milkweed (Asclepiadaceae) family — but has since been changed to a subfamily category.

The Apocynaceae family now contains 5 subfamilies (Apocynoideae, Asclepiadoideae, Periplocoideae, Rauvolfioideae, and Secamonoideae).

It contains 5100 species and 366 genera. There are roughly 50 different species of Gymnema — many of which are used interchangeably.

Many plants in the Apocynaceae family are trees preferring tropical environments — except for a handful of species that prefer to grow in deserts.

 

Clinical Applications Of Gymnema:

Gymnema is mainly used for metabolic conditions including hyperglycemia, hyperinsulinemia, metabolic syndrome, PCOS, hypertriglyceridemia, and both type 1 and type 2 diabetes. Its diuretic and increases the number of pancreatic beta cells.

One of the more unique effects of gymnema is its ability to inhibit sweet flavor. By simply chewing on the leaves, our ability to perceive sweet flavors gradually fades away — helping to prevent excessive sugar intake in habituated individuals.

 

Cautions:

High saponins may cause gastrointestinal upset, caution advised with high doses.

Caution advised if taking hypoglyemic medication due to agonistic interaction.

+ Contraindications

  • Caution advised with hypoglycemic drugs

Iris (Iris versicolor)

iris-versicolor.jpg

What is Iris?

Iris is a misunderstood herb in many circles. It contains a set of constituents that are known to trigger nausea and vomiting — however, somewhat ironically, iris is also considered useful for treating nausea.

This herb has mild laxative qualities — thought to be due to a combination between its potent bitter constituents stimulating the flow of bile from the liver and gallbladder, and an ability to stimulate the parasympathetic nervous system. It's especially active on the liver, where it's used to treat poor digestion, liver dysfunction, and to treat skin conditions.

Other species sometimes used includes Iris caroliniana & Iris virginica.

 

What is Iris Used For?

Iris is used to treat skin conditions through the liver by improving elimination pathways and preventing excessive elimination and irritation through the skin. It's useful for acne, psoriasis, eczema, and rashes.

Other common uses of iris is for urinary tract infection, hypothyroidism, lymphadenopathy, and menstrual irregularities.

+ Mechanisms

  • Thought to stimulate parasympathetic nervous system
  • Iridin thought to induce laxative action due to irritating properties on mucus membranes

Iris has recently seen a peak in interest in the past few years, however, is still not a commonly used herb due to the presence of significant side effects. Iris is contraindicated in anything but small doses due to the mucous membrane irritant and nauseating side effects.

In small doses iris is useful for stimulating bile secretion, promoting movement in the bowels, stimulating the pancreas, and treating skin conditions arising from liver congestion.

 

Cautions:

Some of the constituents in fresh iris root can cause a burning sensation in the mouth and throat along with diarrhea and abdominal burning. It's considered an emetic, and mucus membrane irritant in higher doses. Use cautiously and only in smaller doses.

+ Contraindications

  • Avoid high doses
  • Mucus membrane irritation (IBS, IBD, etc)
  • Diarrhea
