Introduction
There is no absolute distinction between Pudi Lan and Houttuynia cordata in terms of superiority. Pudi Lan is composed of dandelion, skullcap, isatis root, and other ingredients, and primarily functions to clear heat, detoxify, reduce inflammation, and alleviate swelling. It is commonly used to treat heat-related conditions such as pharyngitis and tonsillitis, and has certain inhibitory effects against bacteria like Staphylococcus aureus. It is suitable for individuals with excessive internal heat toxins presenting symptoms such as sore throat and abscesses.

Generally speaking, there is no absolute superiority between Pudilan (Prunella vulgaris) and Houttuynia cordata, as the choice depends on specific symptoms and individual constitution. Detailed analysis is as follows:

Pudilan consists of ingredients such as dandelion, skullcap, and isatis root. It tends to clear heat, detoxify, reduce inflammation, and relieve swelling. It is commonly used to treat heat-related conditions such as pharyngitis and tonsillitis and has certain inhibitory effects on bacteria like Staphylococcus aureus. It is suitable for individuals with excessive internal heat toxins presenting symptoms such as sore throat and abscesses.

Houttuynia cordata has a pungent taste and cold nature, acting on the lung meridian. It is effective in clearing lung heat, relieving abscesses, and expelling pus. It offers auxiliary therapeutic effects for pulmonary inflammations such as pneumonia, bronchitis, and urinary tract infections. It also helps enhance immunity and is suitable for individuals experiencing lung-heat cough with pus-filled phlegm or damp-heat descending causing painful or difficult urination.

When choosing between Pudilan and Houttuynia cordata, one should first determine the hot or cold nature of the illness and individual constitution. Those with cold constitutions should use them cautiously. During use, monitor bodily reactions closely. If symptoms do not improve or worsen, seek timely medical advice for medication adjustment.
