揭秘菟丝子10个害处

1、肠胃不适

如果本身肠胃不好的人群不建议吃菟丝子，菟丝子中富含多种活性物质，服用之后可能刺激肠胃，出现腹痛、腹泻等不适，危害身体健康，尤其本身肠胃虚弱人群会加重病情。

2、导致流产

孕妇是不能吃菟丝子的，菟丝子中的活性物质会引发子宫收缩，从而导致流产或者是早产的情况，威胁胎儿健康，因此吃菟丝子一定要避开孕期服用。

3、引起过敏

个别人群可能对菟丝子过敏，尤其本身易过敏体质更需要注意，避免出现皮肤瘙痒、红肿等不适，严重的还可能威胁生命安全，如果不清楚第一次可以少量尝试，无不适情况再继续服用。

4、加重肝肾负担

吃菟丝子之后需要肝肾代谢，一定要根据自身情况适当服用，避免过量增加肝肾负担，导致肝损伤，危害肝肾功能，尤其本身肝肾功能异常、肝肾功能不全等人群更需要注意。

5、导致上火

菟丝子一定要适量，避免过量导致上火，出现口干舌燥、咽喉不适、失眠、燥热等不适症状，尤其本身阴虚火旺人群更需要注意，避免加重病情。

6、损害身体发育

对于未成年人以及哺乳期女性等人群来说是不能吃菟丝子的，婴幼儿和未成年人身体各个器官都还没发育完善，要避免菟丝子中的成分通过乳汁进入婴幼儿体内，影响身体发育。

7、影响药效

如果在服用降压药、抗凝药或者是降糖药等期间最好不要吃菟丝子，避免影响药效，导致药效增强或降低，如果不清楚最好根据自身具体所服用的药物去咨询医师。

8、头晕

菟丝子一定要适量，避免长期服用，以免长期过量影响神经系统，危害正常的生理功能，从而导致出现头晕、头痛等不适，让日常生活和工作的效率降低，尤其本身日常神经系统比较敏感的人群更需要注意。

9、低血压

菟丝子适当服用能扩张血管，还能降低外周阻力，提高血液流通速度，具有一定的降血压的效果，但是本身低血压人群不适宜服用，避免导致血压过低，出现恶心想吐、视物模糊等不适。

10、心悸胸闷
