Angina, derived from the Latin verb “angere” meaning to strangle, is a clinical manifestation of ischemic heart disease (IHD) characterized by chest discomfort due to inadequate blood flow to the heart muscle. This condition, often precipitated by physical exertion or emotional stress, is typically relieved by rest or nitroglycerin. Angina can present as substernal chest pain, pressure, or discomfort, and may also radiate to the arms, jaw, or upper back, signaling that the heart is not receiving sufficient oxygen. There are various forms of angina, including stable angina, which is predictable and occurs with exertion, and unstable angina, which is more severe and can occur at rest, indicating a higher risk of myocardial infarction. Additionally, variant angina, characterized by spontaneous pain and often associated with coronary artery spasms, and microvascular angina, involving small artery dysfunction without significant coronary artery blockages, further illustrate the diverse presentations of this condition. Understanding these definitions is crucial for appropriate diagnosis and management to prevent adverse cardiac events and improve patient outcomes.

Types of Angina

Angina, a warning sign of underlying heart issues, can manifest in different forms, each with its own unique characteristics and risk factors. Here’s a quick overview of the types of angina to help you understand what they mean for heart health:

• Stable Angina
• Unstable Angina
• Variant Angina (Prinzmetal’s Angina)
• Angina of Effort
• Atypical Angina

Common Causes of Angina

Various factors can trigger or worsen angina, making it essential to understand the common causes behind this condition:

• Significant stenosis of one or more coronary arteries
• Nonocclusive thrombus on preexisting plaques
• Atherosclerosis
• Coronary vasoconstriction or spasm
• Microvascular dysfunction
• Dynamic obstruction
• Progressive obstruction
• Inflammation and/or infection
• Embolism
• Primary dissecting aneurysm of a coronary artery
• Anomalous communication of a coronary artery
• Coronary ostial narrowing
• Systemic diseases affecting intramyocardial arteries
• Myocardial bridge

Best herbs for Angina

Using herbs to care for angina instead of conventional medication offers several potential benefits. Traditional herbs such as Garlic, Guggul, Hawthorn, and Arjuna have been used for centuries to treat cardiovascular disorders, including angina, and recent studies have shown their efficacy in improving cardiovascular health without significant side effects. Additionally, Chinese herbal medicines like Salvia miltiorrhiza and Pueraria lobata have demonstrated effectiveness in improving vascular function and structure in coronary patients, suggesting their potential as a novel agent for secondary prevention. Furthermore, network meta-analyses have indicated that Chinese herbal injections, when combined with Western medicine, can be more effective than Western medicine alone in treating angina pectoris. These herbs not only help in symptomatic improvement but also in reducing cholesterol levels and preventing endothelial inflammatory reactions, which are crucial for managing angina. Therefore, the use of herbs provides a complementary approach that can enhance the overall treatment efficacy and reduce the dependency on conventional medications, which often come with a range of side effects.

1. Herba Rhodiolae

Herba Rhodiolae, also known as Rhodiola rosea or golden root, has shown promising benefits for individuals with angina. This adaptogenic herb has been found to improve cardiovascular function and reduce the frequency and severity of angina attacks. Rhodiola’s cardioprotective effects are attributed to its ability to enhance blood circulation, reduce oxidative stress, and improve the heart’s ability to utilize oxygen efficiently. Rhodiola extract can increase exercise tolerance and reduce chest pain in patients with stable angina, potentially due to its ability to modulate stress hormones and improve overall cardiac performance.

What Research Says?

• Based on research carried out by Complementary Therapies in Medicine, Rhodiola formulations, either alone or in combination with routine Western medicine (RWM), have shown significant improvement in angina symptoms and electrocardiography (ECG) results compared to control groups.

How to Use

To consume Herba Rhodiolae for angina, it is typically recommended to take it in the form of a standardized extract, ensuring a consistent dosage of active compounds like rosavins and salidrosides. The usual dosage ranges from 200 to 600 mg per day, taken in divided doses. It’s best to start with a lower dose and gradually increase it, monitoring for any side effects. Always consult with a healthcare provider before starting any new supplement regimen.

Potential side effects of Herba Rhodiolae

While generally well-tolerated, some individuals may experience mild side effects when taking Herba Rhodiolae. These can include dizziness, dry mouth, sleep disturbances, or mild gastrointestinal discomfort. In rare cases, some people might experience increased anxiety or agitation. It’s important to start with a low dose and monitor your body’s response.

Who should avoid Herba Rhodiolae

Pregnant or breastfeeding women should avoid Herba Rhodiolae due to insufficient safety data. Individuals with bipolar disorder should use caution, as it may potentially trigger manic episodes. Those with autoimmune conditions should consult a healthcare provider before use, as Rhodiola may stimulate the immune system. People with known allergies to plants in the Crassulaceae family should also avoid it.

Interaction with medications

Herba Rhodiolae may interact with certain medications. It can potentially enhance the effects of antidepressants, particularly MAOIs and SSRIs, leading to serotonin syndrome.
