What method of extraction do you recommend for it’s different uses? Specifically I would like to use it for mental health, headaches, depression etc. Would an oil, tincture, tea be best?
Hi Justine!
Thank you so much for leaving a comment on my blog. To use Hypericum for depression I would first consult your health care practitioner, especially if you are on any anti-depressant or anxiety medications, as St. Johnswort can contraindicate with those. For moderate to mild depression, Hypericum can be very effective. I would recommend using it in tincture or tea form for these purposes. Be cautious when taking it for long periods of time as it is photo-sensitizing and prolonged exposure to the sun could lead to burning at a pace faster than normal.
I would also recommend combining it with a few other anti-depressant herbs as I find plants work best in teams (just like people). Things like lavender, lemon balm, blue vervain etc. are very gentle and effective for depression as well. If you have any further questions please don’t hesitate to contact me directly (spiraeaherbs@gmail.com).
I would also encourage you to look into light therapy during the winter months. It has been extremely effective for me. Here is a link to my blog post on it. https://spiraeaherbs.ca/beating-the-winter-blues-light-therapy-part-1/
Good luck!
