Cautions and who should avoid it

St. John's Wort has significant interactions with many medications, including antidepressants (SSRIs), birth control, blood thinners, and other prescriptions — it can make these medications less effective or, when combined with SSRIs specifically, raise the risk of a serious condition called serotonin syndrome. Do not use if taking any prescription medication without first consulting a doctor or pharmacist. May also increase sun sensitivity. Lavender and lemon balm may increase drowsiness with sedatives; discontinue if allergic.
