Reading the research
The evidence key.
Labels describe the state and type of evidence. They are not quality scores, medical advice, or dosing instructions.
Longstanding traditional use is documented; this does not by itself establish clinical efficacy.
Some human research exists, but it is not definitive or may concern a different preparation.
Laboratory or animal research exists without adequate confirmation in humans.
No reliable standardized medical dose is established for the described preparation.
