This article is about western oranges such as Navel orange and Valencia orange, not Mandarin orange (“Mikan” in Japanese). Oranges are believed to improve the flow of Qi in your body. When Qi circulation is stagnant, it is thought to cause various health issues. Consuming oranges may help alleviate these symptoms by promoting better Qi circulation.

While both Western oranges (like Navel and Valencia) and Mandarin oranges are believed to help with Qi flow, Mandarin oranges are classified differently in Yakuzen. Mandarin oranges are considered to have a "warming nature," which means they warm your body. 

Nature – Cool（涼）
