What are the effects of Mars in the 6th house of horoscope?

Mars placed in the 6th house is an enemy-killer. He confers robust physical health and great immunity against diseases. He makes the native energetic, intelligent, courageous, domineering, and lustful. He bestows wealth and prosperity generously, along with a hot temper. These results will come to pass if Mars is well-placed in his own sign, exalted house, or friend's place. Otherwise, opposite effects may be seen.

Hollywood actress Julia Roberts has her Mars sitting pretty in the 6th house!

Julia Roberts shot to fame with the block-buster movie, Pretty Woman. She was the reigning queen of Hollywood for two decades, 1990s and 2000s. In her heydays, she left her competition trailing far behind. She still holds her own. She lost her father at a young age, the 4th house aspect of Mars contributing to it. Her sexual appetite is huge. She had an endless list of boyfriends when not married. Her net worth now is more than $200 mn. It should be noted that Mars is her yogakaraka planet, being the lord of the 5th and 10th houses. And Julia Roberts is known for her controlling ways! That's 6th house Mars illustrated glamorously!
