Sweet potatoes originated in South America and were introduced to Japan from China in the 1600s. In Yakuzen, they are known for replenishing Qi, the body's vital energy. 
They have a neutral property, meaning they neither warm nor cool the body, while also supporting the functions of the spleen and stomach. This makes them a great ingredient for those with a weak digestive system. Additionally, their high fiber content helps prevent constipation.

However, overeating may cause bloating and gas, so it's best to enjoy them in moderation. Pairing them with Qi-boosting ingredients like chenpi can be a good idea.
