Apakah Bunga Prunella (Xia Ku Cao)?
Spica Prunellae (, Xià Kū Cǎo) is the dried fruit spike of Prunella vulgaris, a common perennial herb found throughout temperate Asia and Europe. The spikes are harvested in early summer just as the plant begins to wither — hence its name 'summer-withered grass'. With a bitter, acrid flavour and cold energy, Xià Kū Cǎo enters the Liver and Gallbladder channels to powerfully clear fire, dissolve phlegm, and scatter nodular accumulations.
In TCM, Liver fire rising manifests as red, painful eyes, dizziness, headache, and irritability. Xià Kū Cǎo excels at clearing this fire from the upper body. It is also a key herb for softening and dispersing scrofula (lymph node swellings), goitres, and other phlegm-fire nodules of the neck and throat. Penyelidikan moden has explored its anti-inflammatory, antioxidant, and immunomodulatory constituents, including rosmarinic acid and triterpene saponins.
Sejarah & Asal Usul
Xià Kū Cǎo has been used in Chinese medicine since antiquity, valued both as a medicinal herb and as a cooling summer beverage ingredient across southern China, particularly in Guangdong.

Dissolves phlegm-fire accumulations to soften and reduce enlarged cervical lymph nodes, a use documented since the earliest classical texts.
Goitre & Neck Nodules
