10 Possible Side Effects Of Rhus Coriaria (Sumach)

Rhus coriaria has some side effects when used improperly, such as allergic reactions, gastrointestinal issues, and skin irritations.

These side effects can occur due to overconsumption, cross-reactivity with other allergens, or individual sensitivity.

For instance, an allergic reaction can trigger anaphylaxis, leading to breathing difficulties, or cause skin conditions like urticaria, resulting in discomfort and reduced quality of life.

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

1. Lowers blood pressure

2. Lowers blood pressure

Rhus coriaria induces anaphylaxis in some individuals due to its high content of allergenic compounds such as urushiols.

These chemicals are responsible for triggering a severe allergic response characterized by rapid onset of symptoms including flushing, itching, swelling, and difficulty breathing.

The exact mechanisms behind this reaction are not fully understood, but it is believed that the immune system overreacts to these substances, leading to anaphylaxis in susceptible individuals.

3. Lowers blood pressure

Rhus coriaria triggers hives breakout in some individuals due to its ability to cause an allergic reaction.

The compound gallic acid present in the plant's extracts can stimulate the release of histamine from immune cells, leading to increased blood vessel permeability and subsequent hives formation.

Additionally, the presence of other allergenic compounds like quercetin and kaempferol may also contribute to this adverse effect by triggering an overactive immune response.

4. Lowers blood pressure

Rhus coriaria initiates contact dermatitis in some individuals due to its allergenic properties.

The plant's sap and extracts contain compounds that can cause an allergic reaction when they come into contact with human skin, leading to symptoms such as redness, itching, swelling, and blistering.

This reaction occurs because the immune system overreacts to the presence of these substances, triggering an inflammatory response and resulting in the characteristic signs of dermatitis.

5. Lowers blood pressure

Rhus coriaria releases histamine excess due to its high levels of polyphenolic compounds and flavonoids.

These compounds interact with the body's mast cells, triggering the release of histamine, a chemical mediator that can cause symptoms such as itching, hives, and flushing.

The exact mechanisms behind this effect are not fully understood, but it is thought that the polyphenols in Rhus coriaria bind to histamine receptors, leading to an increase in histamine levels and subsequent allergic-like reactions.

6. Lowers blood pressure

Rhus coriaria enhances skin irritation due to its high concentration of tannins and resorcinolic compounds.

These chemical constituents can cause allergic reactions, redness, itching, and rashes on the skin, particularly in individuals with sensitive skin or pre-existing skin conditions.

The irritating properties of Rhus coriaria can also lead to increased sensitivity, making it essential for users to be aware of these potential effects when using this herb.

7. Lowers blood pressure

Rhus coriaria increases urticaria symptoms.

The use of Rhus coriaria may trigger an allergic reaction in some individuals, causing increased hives or welts on the skin. This is due to the presence of certain compounds such as flavonoids and terpenoids, which can stimulate histamine release, leading to increased urticaria symptoms.

Additionally, Rhus coriaria's high content of salicylic acid may also contribute to its allergenic properties, making it a potential trigger for those with existing urticaria conditions.

8. Lowers blood pressure

Rhus coriaria aggravates eczema conditions due to its allergic properties.

The herb's essential oils and resinous compounds can cause skin irritation, leading to inflammation and itching in individuals with eczema-prone skin. Additionally, the alkaloids present in Rhus coriaria can stimulate the immune system, triggering an overactive response that exacerbates symptoms of eczema.

This reaction is thought to be triggered by the herb's ability to penetrate the skin deeply, causing a heightened allergic response in sensitive individuals.

9. Lowers blood pressure

Rhus coriaria worsens atopic dermatitis due to its ability to stimulate the skin's natural defenses, potentially triggering an inflammatory response in individuals with this condition.

The compound gallic acid present in Rhus coriaria may exacerbate symptoms such as itching, redness, and swelling associated with atopic dermatitis.

This adverse reaction can lead to further discomfort and distress for those already managing this chronic skin condition.

10. Lowers blood pressure

Rhus coriaria causes respiratory distress due to its high allergenic potential.

The plant's sap contains urushiol, a potent allergen that can trigger an immune response in sensitive individuals, leading to symptoms such as wheezing, coughing, and shortness of breath.

Additionally, the plant's aromatic oils can irritate the respiratory tract, exacerbating existing conditions like asthma or bronchitis, and potentially inducing anaphylactic reactions in severe cases.
