摘錄《全國中草藥匯編》 | Modern Research: 現代研究﹕ | Leaves as a vegetable-effect on health. | Side Effects & Cautions: 副作用與禁忌﹕ | People who have diabetes, kidney disease, gout, rheumatoid arthritis or chronic pain in the vulva should avoid sweet potatoes. It is high in oxalic acid that can cause the forming of stones of oxalates and damage the kidneys and can cause pain in joints and in vulva area. It also possesses trypsin inhibiting effect and it can hinder the digestion of protein. A study on New Guinea children death caused by enteritis necroticans related to sweet potato consumption and pork consumption has been reported. There are also a few cases of enteritis necroticans reported in America. Another study shows that certain group of New Guinea men were shorter compared to other groups with the same calorie intake and their main staple was sweet potatoes. Sweet potatoes can also cause the inhibition of the enzyme that kills malaria amoebas and can cause dormant malaria amoebas to flare up. It may also weaken the defense against malaria; so the chances to get malaria become higher. Enteritis necroticans is rarely reported in developed countries. The disease is likely to be under diagnosed. [3] Not to use in cases of pixu (spleen deficient) condition, and or withdampness or yeast Infection. 凡是有以下病症患者忌吃甘薯：糖尿病，痛風，風濕性關節炎，慢性外陰痛。甘薯含高量的草酸，容易導致 化合成草酸鹽结石，傷害腎臟，關節等 。 甘薯有抑制胰蛋白作用而妨礙蛋白質之消化與吸收。 有關於幾內亞的巴布亞小孩患壞死性腸炎與吃 甘薯有關之報導。 有關於某些幾內亞的巴布亞族人比起其他巴 布亞族身高較矮小，雖然所吃的熱量與其他族人相同；但是此族 人主要粮食為甘薯。 甘薯也會抑制能對抗瘧疾變形虫之一種脢。吃甘薯可能引起潜伏中的瘧 疾變形虫而引起瘧 疾發作。也可對瘧 疾變形虫抵抗力降低而較容易得到瘧 疾。 對於壞 死性腸炎，在已發展國家中較少有報導。可能是由於診斷不準確而較少。【3】 脾虛或濕盛 (有念 珠球菌感染或白帶)者 忌吃。 |
