I don't really even know what counts as herbal HRT, as I've never researched it... But out of desperation (lack of acceptance and independence to be able to transition/start HRT) I started drinking spearmint tea regularly at the beginning of this year because I heard it could reduce T, libido, and lead to softer skin. Looking my body beginning to age more masculine now that I've hit 30, I just had to find something, anything to stop any more damage that I could.
Although, in the end, it just wasn't going to be enough for me, so I ended up coming back out to my mom and am planning to go to a therapist soon. I need HRT, the real thing. I do think the tea has dropped my libido down a bit and made my skin softer, but, of course, it's not enough and not where I want to stop... It was just "If I can't have HRT, I must at least have this".
I'd rather be doing all of this under the watch of a doctor so I'm not harming myself. I've heard bad things about blocking T alone. I think I'm okay with the tea, since it's probably only doing it to a lesser extent than an actual T blocker, but you never know.
