Tonifies qi and blood - Pu Tao is used as a mild restorative fruit for fatigue, weakness, palpitations, and depleted constitution after illness or overwork.
Generates fluids and moistens dryness - traditional use includes thirst, dry mouth, and deficiency cough when fluids have been damaged.
Strengthens the sinews and bones - it is sometimes included in tonic-food and medicinal-wine traditions for weak legs, low back fatigue, and rheumatic aching.
Promotes urination - gentle diuretic use appears in traditional guidance for edema and damp accumulation.

Pu Tao Jiu - medicinal wine tradition for weakness, sore sinews, and chronic depletion.
Tonic fruit combinations with Da Zao or Long Yan Rou are traditional food-herb approaches for mild qi-blood weakness and convalescence.
Thirst-relieving preparations use Pu Tao when summer-heat or chronic dryness has consumed fluids without creating intense internal cold.

TCMWiki describes Pu Tao as sweet, sour, and neutral, entering the Lung, Spleen, and Kidney to tonify qi and blood, strengthen tendons and bones, and induce diuresis.
Later Chinese dietetic tradition places Pu Tao among the gentler fruit medicinals that support recovery and dryness without the complexity of harsher herbs.
