Blueheart Herb Whole (Buchnera Hispida)

Blueheart Herb Whole (Buchnera hispida) is the dried whole aerial herb known in Traditional Chinese Medicine (TCM) as Guǐ Yǔ Jiàn (鬼羽箭), a classical heat-clearing and toxin-resolving plant used for soothing inflammation, promoting urination, cooling the blood, and relieving painful swelling. Its nature is bitter, cooling, and dispersing, making it particularly useful for conditions involving heat-toxin, damp-heat, or inflammatory discomfort affecting the throat, skin, or urinary system.

In TCM, Guǐ Yǔ Jiàn enters the Liver and Bladder channels, where it helps cool internal heat, reduce fire-toxin, relieve redness and swelling, and clear damp-heat through urination. It has long been decocted for sore throat, tonsillar inflammation, heat-induced irritability, urinary discomfort, and edema, as well as for skin eruptions, rashes, sores, and local heat swelling. Its cooling, detoxifying action also makes it a traditional remedy for hot, humid seasonal illnesses and inflammatory irritations aggravated by heat.

In folk practice, the herb is frequently used both internally and externally—prepared as washes, compresses, or poultices to calm boils, inflamed skin, and heat rashes, and taken as a cooling tea to disperse heat, ease dryness and scratchiness in the throat, and support urinary clarity.

Modern research shows that Buchnera hispida contains iridoids, flavonoids, phenolic acids, and anti-inflammatory compounds that support its classical functions of reducing swelling, inhibiting microbial overgrowth, cooling blood heat, and promoting smooth urinary flow. These constituents reinforce its traditional role as a gentle yet effective herb for heat-clearing formulas.

Each batch of Blueheart Herb Whole (Buchnera hispida) is carefully harvested and shade-dried to maintain its natural green hue, cooling energy, and clean, mildly bitter profile. When decocted, it produces a light, cooling infusion traditionally used to clear heat, relieve inflammation, soothe the throat and skin, and promote urination to expel damp-heat.
