Wild swimming in winter (or cold showers) as popularised by Wim Hof and others seem to help poor circulation, inflammatory disorders, depression and many other issues. In this Livestream I discuss my thoughts on these practices and show and tell some of the little herbal hacks I use to help recover from cold exposure!

ADDENDUM - I couldn't find the specific reference I saw years ago describing Angelica's ability to improve circulation through the heart - but it seems likely to be the coumarins in the root, which have Calcium-channel blocking activity and act as vasodilators. I recall reading that extracts could specifically increase blood flow through the coronary arteries, if I find the reference I will post it! https://analyticalsciencejournals.onlinelibrary.wiley.com/doi/abs/10.1002/pca.2800030108
