Now that I'm finally off hormonal bc and my cycles have normalized, I find I am EXACTLY synched with the full moon. It makes it feel powerful and auspicious...but it's also a little crazily intense at times! As someone who works in customer service and deals with high volumes of clients every day, I definitely notice the effect that the moon has on the general public. My corporate colleagues used to think I was a crazy hippy when I claimed that I could tell when it was a full moon without looking at a calendar...but now I have them sufficiently convinced that they all have it marked on their calendars so that they can be ready for anything!
For my own moontime, I haven't tried a lot of the classic herbs (motherwort, red clover, etc) so I can't really comment. I don't think that lavender is traditionally a moontime herb, but I find that the emotional support is wonderful. It feels like the kind of big hug that can get you through your day. Someone told me years ago that lavender helps you grieve. It's not something that I've read anywhere else, but I really know where she was coming from. At the time, I assumed she meant that it would help release a much-needed outpouring of grief under difficult circumstances. Now that I have a little more personal experience, I've found it's more that lavender can help you to sit comfortably with darker emotions. A lot of times we have to choose between stuffing down the emotions and letting them all out (not always ideal if it's not the best time). Lavender seems to help me to be ok with feeling negative emotions in a way that doesn't hinder me so much or make me an emotional mess.
We are a way for the cosmos to know itself.
