Consumer Reports is out with a new warning on certain supplements.

FOX's Alex Hein reports: 

This is Housecall for Health.

We recently told you about Consumer Reports warning on caffeine powder, Aconite and Yohimbe, which are unregulated supplements that could have dire effects on the liver and kidney.

Also on the list was Chaparral, which claims to help with weight loss, inflammation, skin rashes and cancer. Coltsfoot is another culprit, promising to help relieve coughs, sore throat, laryngitis, bronchitis and asthma.

Consumer Reports also wants to you steer clear of Comfrey, a possible carcinogen and germander. Greater celandine, green tea extract powder, Kava, Lobelia , red yeast rice and Usnic acid.

According to the report, the above mentioned products post risks to the liver, kidney, muscles, and heart and can trigger hair loss, nerve damage, convulsions and even death. If you're unsure about a product, it's always best to consult your physician.
