Generally, it is recommended to use chamomile, gongju, huangju, and wild chrysanthemum for brewing tea, but the dosage should be controlled when drinking.

1. Chamomile

Chamomile has a bitter and pungent taste, slightly cold nature, and belongs to the kidney, lung, and liver meridians. It has the effect of clearing heat and removing dampness, and can improve damp-heat jaundice after brewing. However, people allergic to chamomile should avoid drinking it to prevent allergic reactions.

2. Gongju

Gongju has a sweet taste and cold nature. It can disperse wind-heat, soothe the liver and improve vision, and clear heat and detoxify. Drinking it as tea can improve symptoms such as red and swollen eyes and sore throat caused by wind-heat colds. However, patients with spleen and stomach deficiency should avoid drinking it due to its cold nature.

3. Huangju

Huangju has a pungent, sweet, and bitter taste, slightly cold nature, and belongs to the lung and liver meridians. It has the effect of dispelling wind and dissipating heat, clearing the liver and improving vision. Drinking it as tea can improve symptoms such as fever, cough, and sore throat caused by external wind-heat and liver fire. People with diarrhea should avoid drinking it to prevent worsening the condition.

4. Wild Chrysanthemum

Wild chrysanthemum has a slightly cold nature and has the effects of detoxifying, dissipating heat, and reducing swelling. Drinking it as tea can improve symptoms such as abscesses, sore throat, headache, and dizziness. However, patients with spleen and stomach weakness should avoid drinking it to prevent discomfort.

In addition, brewing white chrysanthemum tea is also generally beneficial. It has the effects of detoxifying, reducing swelling, and suppressing liver yang, which can improve symptoms caused by wind-heat colds. If the condition is severe, it is recommended to seek medical attention in a formal hospital promptly.
