Oregon grape root is strong medicine and fairly specific medicine. While some herbs are polycrest herbs, meaning they can be used for a wide range of ailments, Oregon Grape Root is more specific in its actions.
“But wait!” you say. “In the plant uses above many different ailments are listed.”
Oregon grape root does two things really well. It addresses infection and it acts on the liver. And, because there are a myriad of problems caused by the liver, Oregon Grape Root is far reaching.
In this monograph we’ll be looking at Oregon Grape Root and its ability to fight infection as well as its affinity for the liver.
A Powerful Anti-microbial in Modern Times

Oregon Grape Root could save the world. 

It’s no exaggeration!
Have you heard of Methicillin-resistant Staphylococcus aureus? This mouthful, also commonly called MRSA, is a serious staph infection in humans that is resistant to pharmaceutical antibiotics.
About 100,000 people die each year in the US due to a MRSA infection. Over two-thirds of the people who contract MRSA can relate it to a hospital visit. MRSA is very serious!
That is where Oregon Grape comes in. A constituent of Oregon Grape Root, berberine, is being studied because it contains a specific multidrug resistance pump inhibitor (MDR Inhibitor) named 5′-methoxyhydnocarpin (5′-MHC)3.
I know that sounds intimidating.
Basically, what this means is that it works to decrease bacterial resistance to antibiotics. A simplified view of how MRSA works in the body is that it has a pump in its cell and when antibiotics enter that cell the pump immediately pumps out the antibiotics so it can have no effect on the MRSA cell.
5′-MHC, which is derived from berberine-containing plants like Oregon grape root, stops that pumping action so the antibiotics can have an effect on the MRSA cell.
Of course drug companies are racing to patent this as a pharmaceutical drug. Some herbalists are using Oregon grape root alongside antibiotics to increase their effectiveness against this deadly infection.
Okay, maybe Oregon grape root isn’t necessarily going to save the world. But that it can be used to address this very serious and deadly infection is powerful news!
Stermitz et al, in Proceedings of the National Academy of Sciences 2000 97:4 also found the presence of 5′-methoxyhydnocarpin in the root. Although in itself it possesses no anti-microbial activity, it strongly potentiates the action of berberine by disabling the bacterial resistance mechanism against both synthetic and natural antimicrobials. The implication is immense for creating synergistic combinations to attack the new breed of antibiotic resistant organisms.
Robert Dale Rogers
No matter how you slice it, Oregon grape root is a strong antimicrobial
Oregon grape root has been used to address minor to severe infections for hundreds, if not thousands of years. It was highly regarded among eclectic physicians for use against syphilis.
Berberis aquifolium has won its reputation chiefly as a remedy for the syphilitic taint. The more chronic the conditions or results of the disease, the more it has been praised. Some claim that if given early it will abort the tertiary stage, but this of course depends in most cases upon the resisting powers of the body and the care the patient takes of himself. 
Harvey Wickes Felter, M.D. (1922)

Today herbalists use Oregon grape root for all kinds of infections24.
  • eye infections
  • vaginal infections
  • wounds on the skin
  • mouth infections1
  • inflammatory bowel conditions
  • infectious diarrhea (e.g., giardia and other parasites)
  • infections in the upper digestive tract (h. pylori)
  • urinary tract infections
  • sore throats

The energetics of Oregon grape root
Seeing this long list of ways herbalists use Oregon grape root to fight infections could seemingly give it the title of an “herbal antibiotic”. However, I find this term to be too simplified and often misleading.
We have a variety of herbs that are anti-microbials, meaning that they have some effect on pathogens. However, each one works in different ways, for different infections, and are best suited to the individual, not the disease.
To understand the complexity of each herb we can study it energetically.
Oregon grape root is bitter, bitter, bitter. I often use it when teaching people about the Taste of Herbs since it really is an archetypal bitter. I often say it is disastrously bitter.
As a bitter it is a cooling, draining and detoxifying herb. (More on detoxifying in the next section about the liver).
Because Oregon grape root cools, drains and detoxifies, it will be most effective when matched to a person who has hot, moist and possibly stagnant conditions. (Although herbalists don’t agree on the humidity factor with Matt Wood and Michael Moore saying it is more specific to dryness.)
Heat in the body is characterized by redness, inflammation, yellow secretions (or a yellow coating of the tongue) and, of course, heat. Moistness in the body is just that: weepy or infections that seep pus or leak fluids, especially fluids that are yellow.
Understanding the energetics of Oregon grape root and the type of person and infection it is best suited to will result in getting consistent effective results.
You’ll often see Oregon grape root referred to as a “berberine-containing plant”. Berberine is a chemical constituent found in several different plants that has been studied extensively. If you like to geek out on constituent studies check out the PubMed database and you’ll find studies showing berberine can lower blood glucose levels, stop infections and modulate inflammation.
Studying plants by their chemical constituents gives new insights or at least a different perspective on plants that wasn’t available to us even 200 years ago. However, it is very limiting and overly simplifying to assume that all herbs that contain berberine are used in a similar manner.
So while plants like goldenseal (Hydrastis canadensis), Barberry (Berberis vulgaris), Goldthread (Coptis trifolia), and Amur cork tree (Phellodendron amurense) all contain berberine, they aren’t necessarily used in the exact same manner. The differentiation between these plants is beyond the scope of what I can cover here.
Today [Oregon grape root] is one of the indispensable articles of herbal materia medica. It was first used as a bitter tonic to promote internal and external secretion in dry and atrophic diseases. Today it is sometimes used (or abused, really) as a “natural antibiotic” because the presence of germ-killing-berberine. This is a materialistic way of viewing a plant by its “active ingredient” rather than by the overall influence of its numerous constituents working together.

Earthwise Herbal: New World Medicinal Plants
Oregon grape root for the liver
Another area that Oregon grape root shines is as an hepatic, or as an herb for the liver.
In western herbalism most bitter herbs are considered to have some effect on the liver and the gallbladder. The bitter taste on the tongue stimulates saliva, which then creates a whole cascade of digestive functions and digestive enzymatic secretions.
Part of the bitter taste reflex is to promote the secretion of bile from the liver and the gallbladder, which helps with digestion, mainly in digesting fats.
Symptoms of a congested liver
Liver congestion is one of the main underlying causes of many issues I see in my clinical practice. Of course each herbal formula I give is specifically formulated for the person and the issues they are having. However, I often use a base combination of dandelion root and Oregon grape root for a wide range of liver issues. In this section we’ll look at a variety of health complaints that could potentially be solved by releasing a stagnant liver.
Seeing a list of liver congestion symptoms could easily lead one to believe that it’s a “fad” diagnosis that is vague and broad. The thing is, the liver performs many functions in the body and, therefore, correcting liver dysfunction can correct a wide range of problems! In Chinese medicine the Liver is considered to be the General of the body because it directs so many physiological functions.
You can read more about the liver from a western physiological standpoint by clicking here.
The liver and the female reproductive system
Because the liver filters hormones, a congested liver can be the root cause of many menstrual problems, including irregular menstruation, flooding, cramping, bloating, headaches and PMS. It can also be the underlying cause of more severe dysfunctions in the female reproductive system, such as endometriosis, ovarian cysts and fibroids. Hepatic herbs like Oregon grape root can be combined with lymphatic herbs and blood moving herbs (and lifestyle changes) to address a variety of these complaints.
The liver and the skin
The liver is a main organ of elimination; when it is not functioning optimally other systems of elimination may be overwhelmed. We can clearly see this with the connection of the liver and the skin. Oftentimes a congested liver can play part of the role in things like skin rashes, eczema and psoriasis. Alterative herbs like Oregon grape root and dandelion are often used for people with these types of skin afflictions.
In moist eczema it has acted most satisfactorily, but has usually been given in conjunction with other treatment. Dr. Soper, in 1884, reported in the Therapeutic Gazette a most intractable case of moist eczema of an acute character covering the entire body. No other alterative was given. The case was cured in four weeks. 
The liver and constipation or sluggish digestion
When the liver isn’t functioning optimally, digestion takes a hard hit! Inability to digest fats, bloating, gas, hemorrhoids and constipation can all be attributed to liver problems. I often add small amounts of Oregon grape root as part of my bitters blends to help move the liver in the case of sluggish digestion.
The liver and the eyes and head
In Traditional Chinese Medicine the liver is associated with the eyes. Dry eyes, red, eyes, excessively tearing eyes, macular degeneration, etc can all have a base in liver function. Also, some types of headaches are caused by poor liver function.
The liver and the musculoskeletal system and energy levels
If the liver isn’t able to filter the blood and remove toxins and metabolic wastes it can result in feeling aches and pains all over. It can also poorly effect energy levels; the liver is especially indicated when a person feels groggy upon waking.
Phew! That was a lot! 
I realize this is a lot of physiology in a monograph, but rather than simply listing all the “diseases” that Oregon grape root is good for, I wanted to give a more thorough explanation of how it all ties together. It’s also important to realize that it is often formulated with other herbs and lifestyle suggestions and is rarely a stand alone treatment. (Although I probably have to qualify that, as some herbalists only practice with simples.)
Energetically we still look for the same indications that we discussed in the section on infection. Heat and excess dampness are great indications. Does the person have a red tongue with a yellow coating? That’s heat. Is their pulse fast and wiry? That’s heat. Do they have eczema that is hot to the touch and weepy? That’s heat.
If someone doesn’t have heat symptoms Oregon grape root could still be used if it were deemed appropriate through other indications. However, more attention would be paid to the formula to ensure that it was a good match for the person.
Currently, western herbalists most often use the roots as herbal medicine, but the leaves and berries have historical and modern uses as well.
Since I have no experience with using the leaves medicinally I’ll rely on Robert Dale Rogers’ historical accounts.
The leaf tea was used for kidney, and stomach ailments, as well as rheumatism and lack of appetite. …the dried leaf is an excellent anti-microbial styptic for herpes and psoratic skin lesions. They contain alkaloids that act on cardiac and smooth muscle as an anti-spasmodic.
Robert Dale Rogers
The young leaves can be eaten. And when I say young I mean it! The older leaves become very tough and quite spiky. The young tender leaves have a slightly sour taste reminiscent of a citrus fruit.

The berries are edible, perhaps not palatable. If the roots are decidedly bitter then the berries can be described as disastrously sour! Most often the berries are added to a lot of sugar before they are considered edible. Jams, pies and wines are made from the berries. The natives in my area dried them and combined them with other sweeter fruits like saskatoon berries.
There are also ethnobotanical records of the berries being used medicinally. Again I’ll rely on Robert Dale Rogers who says…
They also brewed the berries to relieve the ache of sore kidneys.When the berries turned black they were used to treat sores, or put on painful skin boils. They were crushed onto the boil and pulled off when dry and itchy. According to Duke, “California Indians used the berry decoction to stimulate the appetite”
We’ve lost so many ways of using herbs that I think it is important to include historical usage to inspire us to try these methods and re-learn what was lost.
Botanically speaking…
There are multiple “Oregon grape roots” in the Mahonia genus. For this monograph I’ll talk specifically about Mahonia aquifolium. Check your local guidebook for the identifying features of your local variety.
Here is a range map of the Mahonia genus.
Sometimes referred to as Tall Oregon grape, Mahonia aquifolium can grow upwards of 10 feet in the right conditions. More commonly I see it around 4 – 5 feet in height.
The plant can spread through horizontal roots, forming colonies in an area. It thrives in moist soils with sun exposure but is often found growing throughout the forest floor albeit in a shorter and less berry-filled manner.
The leaves are holly-like in appearance and are green with sharp spikes. The leaves tend to be really shiny. These are really sharp! I’ve bled from being too careless around the leaves.
Unlike holly leaves they grow as leaflets. The Mahonia species can sometimes be differentiated by how many leaflets there are. Typically Mahonia aquifolium has 5-9 leaflets.
The flowers are some of the first flowers to appear in the spring and are yellow with parts of six. The flowers are edible, keeping in mind that any you eat won’t turn into berries later in the season. They are slightly sour in taste and are nice sprinkled on salads or as a garnish with meat dishes.
In the late summer and fall the berries can be bursting on these plants, especially if they have access to a lot of water and sunshine.
As the winter comes on some leaves temporarily lose their chlorophyl and become bright red.
The roots can be harvested at any time of the year but are ideally harvested in the fall or early spring.
Ethical Wildcrafting Considerations
Oregon grape root is being threatened with over-harvesting due, in part, to the florist business. Those green leaflets stay vibrant-looking long after they are picked, making them very desirable for arrangements. Keep an eye on your local plants and report any illegal harvesting that you see.
In part due to this, Oregon grape root is on the United Plant Savers to watch list.
When harvesting the root for your personal use, learn how to harvest it sustainably. Horizontal and somewhat superficial roots can be sparingly harvested from the plant, leaving the remaining plant to grow.
Plant Preparations
We typically use the root or, if it is really woody, the root bark in herbal medicine. 
When working with Oregon grape root make sure that your root or root bark is vibrant yellow! If it is no more than a cream color you really don’t have potent medicine. Unfortunately it can be hard to find really yellow roots in commerce.
I mostly use Oregon grape as a tincture, mainly because it is so incredibly bitter it can be hard for people to take as a tea.
It does work as a tea. The tea also works great as an external wash.
Oregon grape root can be used as a dye.
It can also be infused into an oil and made into a salve. Darcey Williamson recommends it combined with willow bark for aches and pains.
Special Considerations
Oregon grape root is not for the cold deficient type. There is some concern that it may interfere with some pharmaceutical drugs.
Oregon grape root excels at treating infections and optimizing a sluggish liver. Its specific considerations are for heat with discharge or moist conditions. It is most often formulated, although it can be used as a simple especially when used for infections. This is abundant and incredibly important herbal medicine.

so, I see the short version growing in the forest out my back door...is this the same thing? or is it salal? it has blue berries in late fall but not sure what the color of the flowers are, I'll have to watch it this summer.

Thank you for posting this, Rosalie. I haven't worked with Oregon Grape Root yet as it isn't a native plant over here. Many people have it growing as an ornamental, including my parents and it's on my list of "pleants to work with in the future". Your stunning photos made me go and look at my parents' plant today and take my own photos. For some reason, despite the frost and bitter cold it is trying to flower and the fruit have long gone. The leaves are turning in the same stunning way as yours so it looks thoroughly confused.

kate kirkham said...

Great piece on O. Grape. I am also fascinated by Berberis nervosa, the small woodland species that you see growing in shady forests near salal. I have only wildcrafted the aquifolium but I'm wondering if you've ever collected nervosa and what the differences in taste, effect and vibe are?

Hi Kate,

I don't have M. nervosa growing near me, so I don't use it. However, herbalists where this is growing use it extensively. Howie Brownstein is a good source of information. I consider them to be entirely interchangeable myself.

Thank you for this lovely information. You wrote it so well! I hope this helps to cure my staph.

My friend made a jelly from this and it was DELICIOUS! served with waffles or on toast etc. He used the common decorative plant that can be found in parking lots etc. Very good.

Karla P. Elliott said...

Rosalee, I have been looking into making my own natural deodorant and one of the recipes I came upon online suggested using 1/4 tsp of oregon grape root powder for those with sensitive skin. How effective is OGR when applied externally?

Rosalee de la Forêt said...

OGR is very effective when applied externally to an infection. Using a 1/4 teaspoon in a (larger) deodorant recipe doesn't sound incredibly useful to me, but definitely wouldn't hurt.

sarah haydock said...

I'm experiencing hormone imbalance (possibly high estrogen) and mild insulin sensitivity... This was such a helpful article, thank you Rosalee. I think Oregon grape could be very helpful for me, except that my one-year old and three year-old children are still breastfeeding, and I have heard cautions about use during breastfeeding... Are there any other herbs that would work similarly but be safer to use during breastfeeding? Dandelion or yellow dock?

Rosalee de la Forêt said...

That's a hard question for me to answer because I don't really think of herbs as being good for "insulin resistance" or "estrogen dominance". Instead I want to know why the person is having those issues, who the person is (constitution) and then build a "formula" around diet/lifestyle and then herbs.

NancyLEE said...

Dear Rosalee - This article has been so helpful to me - Mahonia is my "herb-of-the moment".....I want to pin it to Pinterest but can't find it separate from your other herbal articles. Will you enable pinning just for this article?
Thanks so much.

Rosalee de la Forêt said...

Hi NancyLEE,

So glad you enjoyed the article! I don't have individual pin buttons on my articles. It takes me too long to get it all set up for every article. What you can do is go to the article URL: http://www.methowvalleyherbs.com/2012/11/oregon-grape-root-it-could-save-world.html

And use the Pin IT button from there. I"ll also pin this right now and you can share that from my Pinterest if you like.

Thanks again!

NancyLEE said...

Thanks Rosalee - it's pinned right where I wanted it!
