10 Possible Side Effects Of Actaea Racemosa (Black Cohosh)
Actaea racemosa has some side effects when used improperly, such as headaches, dizziness, and stomach upset.
These side effects are often caused by an overdose or prolonged use of the herb.
For example, a person who uses black cohosh to treat menopausal symptoms but takes too much may experience debilitating headaches, which can interfere with daily life and affect relationships.
This article explains in details the 10 most common side effects of Actaea racemosa if used imporperly.
1. Triggers seizures
Actaea racemosa causes nausea.
The root of this issue lies in the plant's ability to alter digestive processes, potentially disrupting stomach motility and increasing gastric secretions. This may lead to feelings of queasiness and discomfort after ingesting Actaea racemosa.
Additionally, the plant's saponin content can also contribute to nausea by affecting gut bacteria and altering the body's natural balance.
2. Triggers seizures
Actaea racemosa produces dizziness due to its ability to affect the central nervous system.
The plant's active compounds, including isoferulic acid and cimiracemoside, can interact with neurotransmitters in the brain, leading to a sense of lightheadedness or vertigo.
Additionally, Actaea racemosa's sedative properties may also contribute to dizziness as it can slow down heart rate and blood pressure, further exacerbating feelings of faintness.
3. Triggers seizures
Actaea racemosa triggers stomach cramps due to its ability to stimulate digestive processes and increase gut motility.
This can lead to spasms in the smooth muscle of the intestines and stomach, causing cramping and discomfort.
Additionally, black cohosh's saponin content may contribute to its gastrointestinal effects, potentially irritating the lining of the stomach and small intestine and leading to cramps and other symptoms.
4. Triggers seizures
Actaea racemosa increases heart rate due to its stimulatory properties.
The plant's active compounds, such as cinnamic acid and ferulic acid, have been shown to increase sympathetic nervous system activity, leading to an elevation in heart rate and blood pressure.
This increased cardiac activity is believed to be responsible for the tachycardia (rapid heartbeat) experienced by some individuals taking Actaea racemosa supplements.
5. Triggers seizures
Actaea racemosa lowers blood pressure by causing a decrease in peripheral resistance and cardiac output.
This is due to its ability to dilate blood vessels, which allows for increased blood flow and reduced systemic vascular resistance.
As a result, individuals taking Actaea racemosa may experience symptoms of hypotension, such as dizziness, lightheadedness, and fainting.
6. Triggers seizures
Actaea racemosa affects mental clarity by influencing the brain's neurotransmitters, particularly GABA and serotonin.
The herb's saponins may bind to these chemicals, altering their activity levels and potentially leading to feelings of confusion, disorientation, or difficulty concentrating.
This side effect is thought to be caused by the herb's ability to modulate the brain's chemistry, which can result in changes to cognitive function and mental clarity.
7. Triggers seizures
Actaea racemosa induces anxiety in some individuals due to its ability to affect the body's nervous system.
The herb contains triterpene glycosides, which can interact with serotonin and other neurotransmitters, leading to feelings of unease and apprehension. Additionally, black cohosh may stimulate the parasympathetic nervous system, causing a sense of tension and increased heart rate.
This reaction is thought to be related to its traditional use as an herbal sedative, where it helps to calm the mind and body.
8. Triggers seizures
Actaea racemosa causes insomnia due to its ability to affect the brain's neurotransmitters and promote a state of hyperarousal.
The herb's active compounds, such as cimiracemoside A and B, interact with GABA receptors, leading to increased stimulation and difficulty falling asleep.
Additionally, Actaea racemosa may also stimulate the body's natural response to stress, further exacerbating insomnia symptoms.
9. Triggers seizures
Actaea racemosa relieves headaches by acting on the nervous system and affecting the body's response to pain.
When consumed, its active compounds, such as cimicifugin and magnoflorine, interact with neurotransmitters to modulate the transmission of pain signals, thereby reducing headache severity.
Additionally, black cohosh's sedative properties may help alleviate associated anxiety or tension, further contributing to its analgesic effects.
10. Triggers seizures
Actaea racemosa aggravates bronchitis due to its expectorant properties, which can stimulate mucus production and exacerbate respiratory issues.
The herb's ability to increase mucus secretion may overwhelm the lungs and airways, leading to further inflammation and discomfort.
This side effect is attributed to the saponins and flavonoids present in Actaea racemosa, which can cause an overactive cough reflex and worsen bronchial congestion.
