I have used products with Shea butter in it but never pure Shea butter. I just received this and I opened up the tub and this strong diarrhea smell came pouring out of the tub. Is this the way Shea butter is suppose to smell because it is the sickest smell I have ever smelled in my life. I put some on my hands and the smell is deep in my pores. I thought it was suppose to smell nutty and pleasant not like a babies dirty diaper. Maybe it's rancid??
