Is it true that drinking alcoholic beverages like DOM or eating dishes cooked with alcohol will is thought to boost blood circulation and warm up the body?

I've came across an article by Eu Yan Sang (http://www.euyansang.com.sg/beware-these-6-confinement-myths/eysfertility1.html) that clarified this point. The use of alcohol in TCM is believed to help expel cold and promote circulation. However, the article highlighted that nursing mothers should avoid alcohol as it could passed to the baby through breast milk. I guess the use of alcohol should be in moderation and the mother has to be careful not to breastfeed her baby while the alcohol is still within the system.
