Saint John’s Wort (Hypericum perforatum)
For the next few posts, I thought I would review herbs that manufacturers seem to want to add to everything. The first time I really noticed this was with St. John’s wort. ‘It’s treats depression’ would be the implied claim. Smart manufacturers don’t claim that any herb or supplement treats something, unless they have data backed up and filed with the FDA. Anyhow….
St. John’s wort is a great herb, but just like any other herb (I’m looking at you, ma*****na) it is not a panacea for every symptom or disease on earth.
I don’t have a photo of St. John’s wort because I don’t grow it, but I do have a photo of the dried herb being tinctured by percolation:
Yeah – I know it looks like blood. That’s one of the reasons the plant is named after Saint John. I was really surprised by how red it was, especially since I was using dry herb to do this perc.
‘Nerves’ are what I immediately think of with this herb: it is indicated for all types of nerve pain like shingles, trigeminal neuralgia, and chronic pain. It also is good for nervous conditions like anxiety, depression, night terrors, and anorexia. However, I don’t use a lot of Hypericum due to the multiple contraindications it has.
You should not use it in pregnancy due to its emmenagogue effect. It should not be used with most medications due to it being metabolized using the same chemical pathway as many many pharmaceuticals. And it will most likely interact with medications like SSRIs, narcotics, triptans, HIV meds, blood thinners, anticonvulsants, and antirejection drugs.
In my opinion (and just like a particular body part, everyone has one), Saint John’s wort just has too many interactions to just throw into a formula. There are other herbs that don’t have those same issues that work just as well (like lemon balm, elder, mimosa (Albizzia julibrissin, and even chamomile).
I don’t know what started the whole ‘St. John’s wort in everything’ trend – an abundant harvest? A poorly researched study? A carload of it that was about to hit expiration dates? I don’t know. I do know there are better options out there. Just talk to your friendly neighborhood herbalist!
