Passionflower — what independent sources say
NCCIH reports that passionflower has been studied only to a limited extent. Some small studies suggest possible effects on anxiety or sleep, but conclusions are not definitive, and evidence is insufficient for many other promoted uses. NCCIH also notes possible drowsiness, dizziness and interactions around surgery.

Marshmallow root — research context
Marshmallow root is rich in mucilage polysaccharides and has a long history of use for soothing irritated mucous membranes. That background is not the same as evidence for nerve repair or neuropathy treatment. The current Nerve Fresh label confirms its presence, but the role of marshmallow root in the finished formula has not been established by a finished-product clinical trial available to this site.

Corydalis yanhusuo — research and caution
Corydalis yanhusuo contains multiple alkaloids and has a long history of traditional use. Reviews describe pharmacological activity and also safety considerations that vary by preparation. A 2025 analysis found substantial variability in alkaloid content among sampled Corydalis dietary supplements, illustrating why botanical preparation details matter.
Prickly pear cactus
Opuntia ficus-indica contains pigments, polyphenols, flavonoids and other phytochemicals. Reviews discuss a broad range of biological activity, much of it from preclinical or mixed evidence. This does not establish a clinically proven nerve outcome for Nerve Fresh.
California poppy
California poppy contains alkaloids and has traditionally been used in sedative preparations. Laboratory work suggests some extracts can influence drug-metabolizing enzymes, which is one reason to discuss botanical supplements with a healthcare professional if you take medication.
