BOTANICAL IDENTITY
The right name is the first step.
Also known as: No synonyms listed.
The botanical name, part and preparation must match. A photograph is not enough for identification intended for consumption.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
01 · UNDERSTAND
Properties & uses.
Cardiovascular prevention: limited scope
Traditional adjunctive use in preventing atherosclerosis; does not replace any prescribed treatment.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
02 · UNDERSTAND THE ACTION
How does the plant act?
Garlic is studied for several cardiovascular parameters, but a change in cholesterol or blood pressure is not evidence of heart attack prevention. Effects depend heavily on the preparation. The HMPC recognizes traditional adjunctive use, rather than an established treatment for hypertension or hypercholesterolemia. Its effects on platelets also contribute to the attention paid to interactions.
Constituents to know.
Their presence and quantity depend on the plant part and preparation.
- Organosulfur compounds
- Alliinase converts alliin into allicin; crushing, aging and extraction alter the profile. Powder, oil and aged extract do not contain the same sets of substances.Read the reference
Cardiovascular parameters
Research concerns lipids, blood pressure, arterial stiffness and platelets. The report concludes that the data are inconsistent or insufficient for well-established use.
Read the referenceTraditional adjunctive use
Prevention of atherosclerosis falls within traditional complementary use; this must not be taken to mean any prescribed treatment can be replaced.
Read the referenceWhat this means for preparation.
Compare the manufacturing process and exact form, not just milligrams of “garlic.” Have concentrated products checked when taking anticoagulants, antiplatelet agents or certain antiretrovirals.
03 · EXAMINE THE EVIDENCE
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
A useful trial for putting promises into perspective
- Type of research
- Randomized trial cited by the EMA, 192 adults, six months.
- Preparation concerned
- Raw garlic, powder, aged extract or placebo, studied separately.
- Observed results
- None of the three forms significantly reduced LDL in this trial.
- Limitations to consider
- This result illustrates the variability across the dossier; it does not allow all preparations to be declared identical.
What can we take from this?
An experimental antiplatelet effect does not equal demonstrated antithrombotic protection. Laboratory antimicrobial properties do not justify treating an infection with garlic.
