While some people might not think of the linden tree as an herb, I embrace the Herb Society of America’s definition of an herb that includes trees, shrubs, and other plants “valued for their flavor, fragrance, medicinal and healthful qualities, economic and industrial uses, pesticidal properties, and coloring materials.” The lovely linden herb fits that definition well.
The Linden Tree(genus Tilia, also called Lime), shares much of the common symbolism associated with any Sacred Tree in European lore: It’s presence protects against ill luck and against the strike of lightning, and it’s bright nature repels those spirits that would cause harm to the household.
In Germany, linden flower is official in the German Pharmacopoeia, approved in the Commission E monographs, and the tea form is official in the German Standard License monographs (Banz, 1998; Bradley, 1992; Braun, et al. 1997; DAB 10, 1991; Wichtl and Bisset, 1994). It was also official in the pharmacopeia of the former German Democratic Republic (DAB 7DDR, 1972; List and Hrhammer, 1979; Wagner et al., 1984)
