What should Rehmannia (Sheng Di) be combined with to remove damp-heat?

Common combinations of raw rehmannia (Sheng Di) for clearing damp-heat include poria, coix seed, alisma, plantago seed, and phellodendron bark. Raw rehmannia nourishes yin and clears heat, while poria promotes urination and drains dampness. When used together, they simultaneously nourish yin and eliminate dampness. Poria helps expel internal damp-heat through urination, alleviating edema and urinary difficulty caused by damp-heat. Combined with raw rehmannia, this pairing prevents the drying effect often associated with dampness-resolving therapies, making it suitable for individuals with both yin deficiency and damp-heat conditions.

Can Rehmannia glutinosa (Shu Di Huang) and Tribulus terrestris (Sha Yuan Zi) combined with Paeonia lactiflora (Bai Shao) replenish qi and blood?

Under normal circumstances, cooked Rehmannia root (Shu Di Huang) and Tribulus fruit (Sha Yuan Zi) combined with White Peony root (Bai Shao) can nourish qi and blood, but they should be used according to medical advice.
