How to read the evidence

Evidence tier — overall strength of the evidence for the whole compound

StrongWell established — backed by strong, consistent human research.
ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
LimitedVery limited evidence — treat this as a hypothesis, not proof.
InsufficientNot enough good evidence to draw conclusions yet.

Certainty — how sure we can be that the effect is real

Very highVery sure — strong, consistent evidence
HighFairly sure — consistent evidence from good studies
MediumModerately sure — new studies could change this
LowNot sure — little or mixed evidence
Very lowVery unsure — almost no usable evidence

Source — where the data comes from

Meta-analysisPooled analysis of many trials — the strongest evidence
RCTRandomized controlled trial — a strong human study design
ClinicalA human clinical study
Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
Animal researchStudied in animals, not humans
Community reportsAggregated user reports — anecdotal signal, not evidence
TheoreticalMechanism-based reasoning, not yet tested

Study grade — quality of each underlying study (A best, D weakest)

BGood — solid evidence with some limitations
CModerate — limited, small, or mixed-quality studies

Confidence — how strongly the sources back a finding

A 0–100 score from study quality and agreement

Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.

Full write-up

What is it

Angina is a cardiovascular condition. This page focuses on its place within cardiovascular health, including stable angina pectoris as the form referenced in the evidence overview. It is a health condition, not an intervention or product.

Evidence-backed options

Aloe Vera is associated with a 6% NTG-Aloe vera gel formulation described as a possible alternative to conventional sublingual NTG therapy for stable angina pectoris. The reported finding characterizes this formulation as promising, safe, and effective, but it does not establish how quickly any effect appeared or how long the formulation was used.

The population to which this finding applies is also not specified. As a result, the relevance of this option to people with different forms or causes of chest pain, or to those with other health conditions, cannot be determined from the information provided. Evidence should therefore be interpreted in the context of the specific formulation and stable angina, rather than generalized to Aloe Vera products more broadly. Anyone considering options for angina should discuss them with a clinician.

What to avoid

With angina, activities that increase physical demand may be inappropriate when symptoms are active, unstable, new, or brought on by exertion. Cycling can provoke or worsen active or unstable angina. Yoga may also involve exertion, forceful breath retention, or straining, which may be unsuitable when chest pain could indicate active myocardial ischemia. Medical assessment and clearance are relevant before resuming these activities.

Finnish Sauna is flagged particularly for unstable angina because heat exposure may increase myocardial oxygen demand. This makes sauna use a concern when the heart may already be vulnerable to an imbalance between its oxygen needs and supply.

TENS / EMS Therapy is flagged because it is considered contraindicated based on its physiological properties. The available rationale does not specify a more detailed mechanism here, so this point should not be generalized beyond the stated contraindication.

Anyone with new, unstable, or exertional chest pain should seek medical evaluation. A clinician can assess whether an activity is appropriate for the individual’s condition and whether medical clearance is needed.
