Tilia americana or Tilia europea or Tilia cordata
Linden is a tree belonging to different species of the genus Tilia, also known as lime or basswood tree. This herb has been used in European traditional medicine for long to cure an assortment of health conditions. In fact, majority of the linden products available commercially are obtained from the species T. platyphyllos Scop. and T. cordata Mill. Linden is basically a huge deciduous tree belonging to the plant family Tiliaceae that generally grows more than 100 feet tall. While T. cordata Mill. is generally denoted as the small-leaved European linden, T. platyphyllos Scop. is generally known as the large-leaved linden. The fragrant flowers of this genus have a whitish or yellowish hue and are collected during the summer. They are dried soon after collection in a shady location.

Findings of a number of researches undertaken with linden flowers have revealed that the comparative quantities of mucilage and tannin are vital to the flavor of the herbal tea prepared with the flowers.

Linden flowers containing high tannin content (about 2 per cent or more) and comparatively less amount of mucilage help to produce an herbal tea that is high in flavor compared to those prepared with flowers containing lesser amount of tannin and more quantities of mucilage.
It may be noted that mucilage has a propensity to be somewhat bland and this possibly elucidates the reason behind the blooms of T. platyphyllos and T. cordata being preferred as the main source of this herb. These two species of genus Tilia have comparatively more tannin and less amount of mucilage in comparison to the flowers of other species of the genus, for instance, T. tomentosa Moench - commonly known as silver linden.
