Comfrey Leaf Herb Packs Powerful Benefits

(Last Updated On: August 3, 2018)

Herbal medicine is also known as herbalism or botanical medicine, and it is an alternative medical system based on the use of plants or plant extracts to treat illness and disease.

Herbs have been used for many thousands of years by different cultures around the world. Herbal remedies can be ingested, applied topically to the skin, or taken in the form of capsules and tablets which is a generally more concentrated form.

Herbal remedies are increasingly being used alongside, or as an alternative to, conventional medicine, as people become disgruntled with unwanted side effects from drugs, and their spiralling cost. People find that in general, herbs are gentler on their system, and that instead of just treating symptoms, they restore balance, and therefore good health.

Rather than just treating diseases once they have occurred, many cultures use herbal remedies to prevent them, for example, turmeric is linked to a reduced risk of cognitive disease, and in India, where the spice is widely consumed, older people have one of the lowest rates of Alzheimer’s disease in the world.

The pros and cons of herbal medicine

Herbal medicine has been used for thousands of years, and herbal remedies are gentler on the system in general. But natural does not always mean safe, and if you are considering using a herbal remedy, get qualified advice, and make an informed decision about what is best for you and your health.

The benefits of using herbal medicine

Comfrey leaves are commonly used in gargles and mouthwashes

Less risk of side effects

Most herbal medicines are gentle on the system, and are better tolerated than drugs. They may be safer to use over time and produce considerably less side effects than traditional medicines. Being unable to tolerate side effects is a major reason for the discontinuation of medication.

They are effective for chronic conditions

Herbal medicines tend to be more effective for chronic health concerns, especially those that don’t respond to traditional medicine. For example, the herbs used to treat arthritis. One of the most well-known drugs for the treatment of arthritis, Vioxx, was recalled due to an increased risk of the patient developing cardiovascular problems. Herbal treatments for the condition have few or no side effects and have been shown to be effective, when taken in conjunction with lifestyle changes.

They are cheaper

Herbs cost far less than traditional drugs. Drugs have to be researched, tested, and marketed, which makes their cost spiral. Herbal medicines are naturally derived and tend to cost far less.

They are widely available

Herbs don’t need a prescription, and there are some herbs, like peppermint and chamomile, that you can grow at home. In some remote regions of the world, herbs might be the only available treatment for health problems.

The cons of using herbal medicine

Herbs are natural, but it does not mean that herbs are appropriate all of the time.

They are not appropriate for serious conditions

Serious health problems such as a heart attack, appendicitis, or a broken limb is far better treated with modern medicine, diagnostic tests, and surgery.

Sometimes there is a lack of information on dosages

Many herbs do not come with instructions on how much to take, like you get with modern medicines, so there is a real risk of taking enough to cause you harm.

Wild herbs can be poisonous

Comfrey has soothing properties so it can help to cure a cough

If you can’t correctly identify a herb, or you use the wrong part of it, there is a risk that it can cause poisoning.

They can interact with medication

Herbal treatments can interact with medications. Nearly all herbs come with a warning to this effect, and many, like the herbs used for anxiety and depression, such as Valerian and St. John’s Wort, can interact with prescription medication like antidepressants and the contraceptive pill. It’s important to discuss your medications and herbal supplements with your doctor to avoid potentially dangerous interactions. Natural does not always mean safe!

They are not regulated

Herbal products are often unregulated, unlike prescription drugs. There is the potential of buying products that are inferior in quality, and because standards can vary so much, there is no way of knowing exactly how much to take.


Comfrey leaf has been used as a healing remedy for thousands of years. It was widely used in North America and Europe. There is quite a lot of debate about how safe it is however, as some parts and compounds of the plant contain alkaloids; compounds which are potentially toxic. The safety of the herb all depends on the part of the plant you use, what species of it you use, and how it is harvested, and there is evidence to suggest that it is safe to use if used sensibly and with caution.

The plant is a member of the Borage family, and there are about 35 different species of the plant. Comfrey has large, rough leaves with white, pink, or purple flowers. It is native to Europe, and flourishes in Asian regions like Caucasus, Kazakhstan, Siberia, and Turkey. It is also commonly found as a weed in more northern and temperate climates.

The name comfrey comes from the Latin term ‘con firma’ which means ‘knitting together’. This comes from the idea that the plant was used to heal bones traditionally.

The plant is best harvested when the flowers are just starting to bud. The alkaloid content varies depending on the season. The highest amount of alkaloids are found early in the harvest.

The history of comfrey

The Ancient Greeks and Romans noted many of comfrey’s benefits, and the plant was cultivated in gardens for many thousands of years. Traditionally, its main uses were to heal wounds, and to treat strains, sprains, and broken bones.

Comfrey can be used as a fertilizer

Comfrey enriches compost and makes it more nutrient rich. Piles of comfrey leaves can be dried with heavy water buckets on top of them to make a concentrated liquid fertilizer. It will have a pungent smell but it is very effective in the preparation of manure, and will add plenty of nutrients to the soil.

Is comfrey safe?

Are there any significant drug interactions associated with comfrey?

Comfrey appears to be generally safe when applied to unbroken skin in small amounts. However, the potentially poisonous chemicals present in comfrey can still pass through the skin, so they can still be absorbed if your skin is broken or if large amounts are administered. It is considered unsafe to take comfrey by mouth because of these chemicals, which are known to cause liver damage, lung damage, and cancer. The US Food and Drug Administration has recommended banning all oral forms of comfrey for this reason.

However, some advocates argue that the chemicals, known as pyrrolizidine alkaloids (PAs) in comfrey are overall less toxic than those found in known poisonous plants, such as ragwort. It also raises doubts whether the chemicals could cause cancer outside of the lab tests, and argue that a study has shown that if comfrey is used properly, it does not cause toxicity or death.

As you are always reminded however, even though comfrey is natural, this does not mean that it can’t cause problems. Use it topically in small amounts, and avoid ingesting it. Avoid it completely if you are pregnant or breastfeeding, and don’t allow children or the elderly to ingest it. There is a lack of evidence about how safe it is for use by these at risk groups.

Are there any significant drug interactions associated with comfrey?

There are no known reports of interaction between comfrey and conventional drugs, however, some herbs that have been known to cause liver problems, such as kava, skullcap, and valerian, should not be used alongside comfrey products because there is an increased risk of liver damage.

Final thoughts

Comfrey appears to be generally safe when applied to unbroken skin

Herbal medicine is being used increasingly alongside conventional medicine, or indeed, instead of it. As people look for a solution to their health concerns, they are increasingly turning to alternative remedies, as side effects and the spiralling cost of drugs makes the alternative seem much more attractive.

Plant-based medicines have been used for thousands of years to treat many different ills. In fact, many of the drugs we use today are derived from plant-based compounds.

Herbal remedies can be used for just about health concern you could name. They are cheaper, more available, and are easily used as part of a healthy lifestyle.

However, remember that just as herbal medicines have their place, they cannot completely replace conventional medicines, as herbs definitely won’t treat very serious problems such as heart attacks, appendicitis, or limb fractures.

As herbs are largely unregulated, there is often no recommendation on safe dosage. Add to this that the potency of the herb will depend on many variables such as how it was harvested and grown and how pure it is, then you can see how this becomes increasingly uncertain.

Comfrey has long been used to treat joint sprains and strains, and it turns out that the humble plant can actually be used for much more than this. It’s great for the skin and hair, and it combats infections. Mother Nature has definitely worked her magic again with this one!
