👉 The heather fluid, also known as heather acid or heather tannin, is a complex mixture of organic compounds found primarily in the leaves and stems of heather plants. This fluid acts as a defense mechanism against herbivores and pathogens, providing the plant with chemical resistance. It contains various phenolic compounds, including tannins, flavonoids, and other secondary metabolites that deter feeding by insects and animals due to their astringent taste and potential toxicity. Additionally, the heather fluid plays a role in plant communication and stress response, helping to protect the plant in its natural habitat.
