10 Possible Side Effects Of Crataegus Oxyacantha (Hawthorn)

Crataegus oxyacantha has some side effects when used improperly, such as gastrointestinal disturbances, headaches, and dizziness.

These side effects are often caused by excessive consumption, interactions with other medications, or allergic reactions.

For instance, individuals with pre-existing kidney or heart conditions may experience severe complications, such as cardiac arrhythmias or kidney damage, which can severely impact their quality of life, leading to fatigue, pain, and reduced mobility.

This article explains in details the 10 most common side effects of Crataegus oxyacantha if used imporperly.

1. Worsens thyroid function disorder

Crataegus oxyacantha causes allergic reactions in some individuals.

This is due to the presence of a unique compound called flavonoids, which can trigger an immune response in susceptible people. Additionally, the plant's extracts may contain small amounts of latex, a common allergen that can cause skin irritation and other symptoms.

These allergic reactions can range from mild to severe, including symptoms such as hives, itching, and respiratory issues.

2. Worsens thyroid function disorder

Crataegus oxyacantha triggers blood pressure spikes due to its ability to increase cardiac output and peripheral resistance.

The herb's flavonoids and procyanidins work together to enhance the heart's pumping capacity, leading to increased systolic blood pressure. Additionally, Crataegus oxyacantha may cause a constriction of blood vessels, further contributing to the elevation in blood pressure.

This side effect is typically seen in individuals who already have hypertension or are taking medications that affect blood pressure.

3. Worsens thyroid function disorder

Crataegus oxyacantha increases heart rate rapidly due to its ability to stimulate the cardiovascular system.

The herb's bioactive compounds, such as flavonoids and oligomeric proanthocyanidins, can cause vasodilation and increased cardiac output, leading to a rapid increase in heart rate.

Additionally, Hawthorn's effects on the nervous system may also contribute to this side effect by stimulating the sympathetic nervous system and increasing catecholamine release.

4. Worsens thyroid function disorder

Crataegus oxyacantha induces gastrointestinal upset.

This side effect may occur due to the presence of anthraquinones and flavonoids in the plant, which can irritate the digestive tract and lead to symptoms such as nausea, vomiting, and diarrhea. Additionally, the saponins present in hawthorn may also contribute to this adverse reaction by altering the gut flora and causing changes in bowel habits.

These compounds may interact with the digestive system, resulting in an unpleasant side effect profile.

5. Worsens thyroid function disorder

Crataegus oxyacantha produces dizziness commonly due to its ability to alter blood pressure and heart rate.

The flavonoids present in the plant can cause a decrease in blood pressure, leading to feelings of lightheadedness or dizziness.

Additionally, the cardiovascular effects of Crataegus oxyacantha, such as increased cardiac output and peripheral resistance, may also contribute to this side effect.

6. Worsens thyroid function disorder

Crataegus oxyacantha activates liver enzyme damage due to its high concentration of flavonoids and anthocyanins.

These compounds can alter the body's metabolism and disrupt the normal functioning of liver enzymes, leading to an increase in cytochrome P450 activity.

This increased activity can result in the breakdown and elimination of certain medications, potentially causing adverse effects on the user.

7. Worsens thyroid function disorder

Crataegus oxyacantha provokes kidney stone formation by inhibiting the excretion of oxalate, calcium, and uric acid in urine.

This may occur due to its ability to reduce urinary pH levels, increasing the likelihood of these minerals precipitating out of solution and forming stones within the kidneys.

Additionally, hawthorn's potential to decrease blood flow and increase pressure in the kidney may further contribute to stone formation by concentrating mineral deposits within the renal tubules.

8. Worsens thyroid function disorder

Crataegus oxyacantha stimulates menstrual irregularities due to its potential to affect hormonal balance.

The plant's bioflavonoids and other compounds may interact with estrogen receptors, leading to changes in menstruation patterns, such as delayed or prolonged periods, heavier or lighter bleeding, and disruptions to the normal monthly cycle.

This is thought to be a result of the herb's ability to influence the body's hormonal regulation, which can have unintended consequences on reproductive cycles.

9. Worsens thyroid function disorder

Crataegus oxyacantha affects mental alertness negatively as it can cause drowsiness and fatigue in some individuals.

This is due to its ability to interact with the body's central nervous system, leading to a sedative effect on the brain.

Additionally, hawthorn may slow down reaction times and impair cognitive function, potentially impacting daily activities that require mental clarity and focus.

10. Worsens thyroid function disorder

Crataegus oxyacantha enhances skin rash occurrence due to its high concentration of flavonoids and triterpenic acids.

These compounds can cause an allergic reaction in some individuals, leading to the development of a rash.

The exact mechanism behind this side effect is not fully understood, but it's believed that the chemicals present in hawthorn interact with the skin's natural barrier, triggering an immune response and resulting in inflammation.
