He Zhengzheng and Wang Laoji are both good, mainly depending on personal needs and tastes. From the perspective of composition, the formula of Zhenghe and Wang Laoji is different, so the efficacy is also different. Heqizheng herbal tea is mainly composed of honeysuckle, chrysanthemum, dandelion, plantain and other medicinal materials, which has the effects of clearing away heat and toxic materials, diuresis and detumescence. Wang Laoji herbal tea mainly contains Chinese herbal medicines such as Prunella vulgaris and licorice. These components have the functions of clearing away heat and toxic materials, moistening lung and relieving cough. Therefore, consumers can choose their own herbal tea according to their own needs, which is quite different from Zheng Qi and Wang Laoji in taste. Heqizheng herbal tea has a refreshing taste and moderate sweetness, which is suitable for drinking in hot summer. Wang Laoji herbal tea, on the other hand, is rich in taste and has a certain medicinal flavor, which may be more suitable for consumers who like strong medicinal flavor. Therefore, consumers can also choose according to their own tastes.
