What Is Hawthorn?

Hawthorn is a flowering shrub or small tree belonging to the Crataegus genus in the rose family, Rosaceae. There are many species of hawthorn, including Crataegus monogyna, Crataegus laevigata, Crataegus mexicana, and Crataegus pinnatifida. Depending on the species, hawthorn may also be known by names such as common hawthorn, English hawthorn, Chinese hawthorn, or tejocote.

Hawthorn is recognizable by its small white or pinkish flowers, thorny branches, and berry-like fruits, which may range from red to dark red. The leaves, flowers, and fruits have all been used in traditional herbal practices.

Hawthorn has a particularly strong history of use in traditional herbalism for heart and circulatory wellness, although it has also traditionally been used for digestion, circulation, and general wellness.

Modern herbal products may contain hawthorn as a dried herb, powdered plant material, tea, liquid extract, or standardized botanical extract. The exact composition can vary considerably depending on the species, plant part, growing conditions, and extraction method.

Where Does Hawthorn Come From?

The name "hawthorn" refers to numerous species within the Crataegus genus. Hawthorn species naturally occur throughout temperate regions of the Northern Hemisphere, extending across parts of Europe, Asia, North America, and into Central America.

For example, Crataegus monogyna, commonly called common hawthorn, is native from Europe through the Caucasus and into parts of North Africa and Iraq. Other hawthorn species are native to North America, while several species are native to China and other parts of Asia.

Because there are many species, "hawthorn" should not always be treated as though it refers to one identical plant. Different species can have different traditional uses and different concentrations of naturally occurring plant compounds.

Hawthorn belongs to the same botanical family as apples, pears, roses, and many other familiar plants. Its berries are sometimes used in traditional foods and herbal preparations.

How Is Hawthorn Used?

Hawthorn has a long history in traditional herbal practices. Different parts of the plant may be used for different purposes.

Hawthorn Leaves and Flowers

Hawthorn leaves and flowers are among the most commonly studied parts of the plant. European herbal preparations may use dried or powdered leaves and flowers, fresh plant juice, or liquid and dry extracts.

Traditionally, hawthorn leaf and flower preparations have been associated particularly with circulatory and cardiovascular wellness and with periods of temporary nervous tension or stress.

Hawthorn Berries

Hawthorn berries have also been used traditionally in herbal preparations and foods. Depending on the species, the fruits can contain naturally occurring flavonoids, phenolic compounds, and other plant constituents.

Hawthorn berries are sometimes prepared as teas, extracts, powders, syrups, or traditional food preparations.

Hawthorn Tea

Dried hawthorn leaves, flowers, or berries may be used to prepare herbal tea. Tea provides a traditional way of incorporating the plant into a wellness routine without necessarily using a concentrated extract.

Hawthorn Extracts and Supplements

Hawthorn is also available in capsules, tablets, tinctures, and standardized extracts. Concentrated extracts can contain substantially different amounts of plant compounds than a simple tea, so products should not automatically be considered equivalent simply because they contain "hawthorn."

What Are the Benefits of Using Hawthorn?

Hawthorn has traditionally been valued primarily for heart and circulatory wellness. Scientific research has investigated several potential areas of interest, although the strength of evidence varies.

Cardiovascular Wellness

Hawthorn is one of the better-studied traditional herbs in the area of cardiovascular health. Researchers have investigated hawthorn preparations in people with cardiovascular conditions, particularly heart failure.

Some clinical studies have reported improvements in measures such as exercise capacity and symptoms when certain standardized hawthorn extracts were used alongside conventional treatment. However, results have not been consistent across all studies.

Because heart conditions can be serious, hawthorn should not be viewed as a replacement for prescribed cardiovascular treatment.

Circulation Support

Traditional herbal systems have used hawthorn in connection with healthy circulation. Its naturally occurring flavonoids and other polyphenolic compounds have attracted scientific interest because of their antioxidant and vascular effects observed in laboratory and experimental research.

However, laboratory findings do not automatically mean that taking hawthorn will produce the same effect in humans.

Antioxidant Properties

Hawthorn contains naturally occurring plant compounds, including flavonoids and phenolic compounds, that have antioxidant activity.

Antioxidants help protect cells from oxidative stress by interacting with reactive molecules. This is one reason hawthorn continues to be studied as a botanical ingredient for general wellness.

Traditional Digestive Use

Historically, hawthorn has also been used in traditional herbal practices for digestive wellness. The berries in particular have a long history of traditional food and herbal use in different cultures.

Scientific evidence supporting hawthorn for specific digestive conditions is much more limited than the research surrounding cardiovascular applications.

Traditional Stress and Nervous-System Uses

Hawthorn has traditionally been associated with calming and general wellness practices. European herbal references have included hawthorn leaf and flower preparations in the context of temporary nervous tension or stress.

Research into hawthorn and anxiety remains limited, and more evidence is needed before firm conclusions can be made.

What Makes Hawthorn Interesting to Researchers?

Hawthorn contains numerous naturally occurring phytochemicals. Among the compounds researchers have investigated are:

• Flavonoids

• Phenolic compounds

• Oligomeric procyanidins

• Triterpenes

• Other polyphenolic plant constituents

The amount and combination of these compounds can vary depending on the species of Crataegus, which part of the plant is used, where it was grown, and how it was processed.

This variation is particularly important when comparing scientific studies. A study using a standardized extract of one Crataegus species cannot necessarily be used to make the same conclusions about every hawthorn tea, powder, or supplement.

Scientific Research on Hawthorn

Hawthorn has been the subject of clinical trials, systematic reviews, and meta-analyses, particularly in relation to cardiovascular health.

One meta-analysis of randomized, double-blind, placebo-controlled trials involving people with chronic heart failure found that certain hawthorn extracts were associated with improvements in measures such as maximal workload, pressure-heart-rate product, fatigue, and shortness of breath. The researchers concluded that hawthorn showed potential as an adjunctive treatment, while also noting that additional research was needed.

More recent research has continued to examine hawthorn and blood pressure. A 2025 meta-analysis of six randomized placebo-controlled trials involving 428 participants reported a statistically significant reduction in systolic blood pressure, although the researchers noted limitations and the need for additional high-quality research.

Importantly, the National Center for Complementary and Integrative Health (NCCIH) currently describes the evidence for hawthorn as mixed. There is not enough high-quality evidence to determine whether hawthorn can prevent or treat heart disease, angina, abnormal heart rhythms, or arterial plaque buildup.

In other words, hawthorn is scientifically interesting, but research does not justify treating it as a cure or replacement for medical treatment.

Hawthorn and Heart Health: What Does the Evidence Really Say?

The heart is the area where hawthorn has received the greatest amount of scientific attention.

Research suggests that some standardized hawthorn preparations may influence cardiovascular function, but different studies have produced different results. The species of hawthorn, plant part, preparation, dosage, and length of use can all influence research outcomes.

For this reason, it is more accurate to say that hawthorn has potential cardiovascular-supportive properties that are being studied rather than claiming that hawthorn treats or cures heart disease.

Anyone with heart disease, high blood pressure, an irregular heartbeat, or another cardiovascular condition should discuss hawthorn with a qualified healthcare professional before using it.

Hawthorn Safety and Important Considerations

"Natural" does not automatically mean risk-free.

NCCIH reports that possible side effects of hawthorn may include dizziness, nausea, vomiting, diarrhea, and muscle pain. Research on long-term safety is limited.

Hawthorn may also interact with medications. Anyone taking prescription or over-the-counter medication—particularly medication related to the heart or blood pressure—should consult a healthcare professional before using hawthorn supplements.

There is also limited information about the safety of hawthorn during pregnancy and breastfeeding.

A Special Note About Tejocote

Consumers should be particularly careful with products marketed as "tejocote root." Tejocote is associated with Mexican hawthorn (Crataegus mexicana), but the FDA has warned about products labeled as tejocote root that actually contained toxic yellow oleander.

This is an important reminder that botanical identification and responsible sourcing matter when purchasing herbal products.

Hawthorn in Traditional Herbalism

Hawthorn's popularity in herbalism is largely connected to its long-standing relationship with heart and circulatory wellness.

Traditional herbalists have used various parts of the plant for generations, while modern researchers have attempted to identify which plant constituents may explain some of these traditional applications.

Today, hawthorn remains an important botanical in the world of herbal wellness and continues to be studied for its potential cardiovascular, antioxidant, and other properties.

How to Choose a Hawthorn Herbal Product

When purchasing hawthorn, consider the following:

1. Identify the species.
Look for the botanical name when available. "Hawthorn" can refer to many different Crataegus species.

2. Know which part of the plant is being used.
Leaf, flower, berry, and root preparations are not interchangeable.

3. Look at the preparation.
A tea, whole-herb powder, tincture, and standardized extract can have very different concentrations of plant constituents.

4. Choose reputable sources.
Responsible sourcing and accurate botanical identification are especially important with hawthorn because different species can look similar and botanical substitutions can occur.

5. Consider your medications.
If you take medication, particularly cardiovascular medication, consult your healthcare professional before adding concentrated hawthorn to your routine.

Hawthorn as Part of a Natural Wellness Lifestyle
