Holy Basil benefits

hey guys, just got this and I'm reading about how it's dangerous to swallow (and should be mixed with some fatty agent like olive oil and applied topically) but then others say it's fine by mouth just a drop or maybe two.

As I understand this is the same as Griffonia, and should help recapture Serotonin and help with relaxation, mood and possibly sleep. Any first hand experience you wanna share ? Would love to read some anecdotes, good or bad
