Essential oils make boys grow breasts

Parents listen up! If you don't want your boy to grow breasts, then you should not let him use shampoos, soaps and lotions that contain lavender and tea tree oils. From CNN:
The three boys were brought to their doctors with overdeveloped breasts that looked like those of girls in early puberty. They were sore in one case. For each boy, doctors could tie the problem only to their use over several months of the natural-oil products.

The researchers suspected that the oils might be upsetting the boys' hormonal balance. So they did a series of laboratory tests to check how these oils work within human cells. The oils appeared to mimic estrogen and block the male hormone androgen.

On product labels, the oils sometimes are listed by their scientific names: Lavandula angustifolia (lavender oil) and Melaleuca alternifolia (tea tree oil). Such products do not require government approval to be sold unless they make specific health claims...

Dr. Clifford Bloch, a hormone specialist in Greenwood Village, Colorado, who treated the three boys, recommended that parents "be cautious" with such products, especially for prolonged use. "I would not give these products to my children," he said in an interview.
