10 Possible Side Effects Of Tussilago Farfara (Coltsfoot)

Tussilago farfara has some side effects when used improperly, such as digestive issues, allergic reactions, and interactions with medications.

Overuse or excessive consumption can cause stomach upset, nausea, and diarrhea, while allergic reactions can range from mild itching to severe anaphylaxis.

In rare cases, coltsfoot can exacerbate respiratory conditions or worsen symptoms of asthma or chronic bronchitis, severely impacting daily life.

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

1. Interferes with blood clotting processes

Tussilago farfara irritates skin when applied topically due to its high concentration of saponins and flavonoids.

These compounds can cause an allergic reaction or skin irritation in some individuals, leading to redness, itching, and inflammation. The skin's natural barrier is disrupted by these potent chemicals, allowing water to escape and causing dryness and discomfort.

As a result, topical application of Tussilago farfara may not be suitable for everyone, particularly those with sensitive skin.

2. Interferes with blood clotting processes

Tussilago farfara interacts with certain medications negatively.

This can lead to a range of side effects, including dizziness, lightheadedness, and increased sensitivity to the medication's effects. The culprit behind these interactions is the plant's ability to alter the metabolism and processing of certain drugs in the body, making them more potent or causing an excessive buildup of their active ingredients.

This can have unpredictable consequences, depending on the specific medication involved.

3. Interferes with blood clotting processes

Tussilago farfara increases blood pressure temporarily due to its stimulatory effects on the nervous system.

The herb contains compounds such as flavonoids and saponins that can cause vasoconstriction, leading to a temporary rise in blood pressure.

Additionally, coltsfoot's bitter and cooling properties may also contribute to this effect by stimulating the sympathetic nervous system, which regulates heart rate and blood vessels' diameter.

4. Interferes with blood clotting processes

Tussilago farfara induces nausea and vomiting quickly due to its high content of pyrrolizidine alkaloids.

These toxic compounds can cause gastrointestinal irritation, leading to unpleasant symptoms such as queasiness, vomiting, and stomach discomfort when ingested in large quantities or for extended periods.

The body's attempts to eliminate the toxins through the digestive system can also exacerbate these adverse reactions.

5. Interferes with blood clotting processes

Tussilago farfara produces dizziness or lightheadedness frequently.

This is due to the herb's ability to stimulate the central nervous system, leading to a temporary increase in blood pressure and heart rate.

The saponins present in Tussilago farfara may also cause vasodilation, further contributing to decreased blood flow to the brain, resulting in feelings of dizziness or lightheadedness.

6. Interferes with blood clotting processes

Tussilago farfara affects kidney function severely.

The compound glycoside of tussilagin in the plant may interfere with the body's natural ability to excrete waste products, leading to a buildup of toxins and potentially harming kidney function.

Additionally, the presence of anthraquinone derivatives in Tussilago farfara may exacerbate existing kidney issues or even cause irreversible damage if taken for extended periods.

7. Interferes with blood clotting processes

Tussilago farfara stimulates excessive salivation initially due to its mucilage-rich composition and soothing properties.

The saponins present in the plant's leaves and flowers have a stimulating effect on the salivary glands, leading to an increase in saliva production.

This excessive salivation is a common side effect when using Tussilago farfara, particularly in its raw or unprocessed form.

8. Interferes with blood clotting processes

Tussilago farfara causes stomach upset occasionally.

This is due to its high content of tannins and saponins, which can irritate the mucous membranes in the digestive tract, leading to discomfort, nausea, and abdominal pain.

The herb's bitter compounds may also slow down digestion, causing stomach upset and potentially triggering symptoms such as bloating and cramping.

9. Interferes with blood clotting processes

Tussilago farfara irritates eyes when ingested accidentally.

This is because it contains toxic compounds, such as saponins and glycosides, which can cause irritation and inflammation in the eyes. The mucilage present in the plant can also bind to the cornea, further exacerbating discomfort.

As a result, accidental ingestion of coltsfoot can lead to redness, itching, and tearing of the eyes.

10. Interferes with blood clotting processes

Tussilago farfara increases heart rate and palpitations.

This side effect is due to its stimulatory properties on the nervous system, which can cause an increase in sympathetic activity. As a result, the heart beats faster, leading to an elevated heart rate and palpitations.

Additionally, the herb's expectorant properties may also contribute to this side effect by stimulating the vagus nerve, which regulates heart function.
