in addition to the benefits of linden you mention in the video...
here in Bulgaria we use it mostly in winters... especially in cases of cold symptoms!
it relaxes & cleanses the throat and lungs if coughing...
as a kid i did make often inhalations of the steamed linden flowers ;)

another wonderful property of its flowers is... when they blossom in june and when it rains ..the whole town smells amazing :)
(just like a fresh tea)

we have a lot of linden trees around the streets in front of houses and even in downtown :)
it is some form of tradition to have a tree in front ~ for health and prosperity ;)
i have 3 small trees in the backyard which sprouted from seeds.
still haven't blossomed, despite they're like 4-5-6 years old...
