I was suggested Shen Gem by a Holistic Health Practitioner when I was overwhelmed and stressed. It has helped me immensely with stress, heart palpitations and anxiety. I've heard it's also great with insomnia, racing thoughts at bedtime but that was not my issue. However, I've tried to "go off of it," but it has become something I really need to take everyday, like a vitamin and I am ok with that. It's also helped me with PMS, as I am a female. This is a 5 star supplement for me, I do not know what I would do without it: a calming buffer and centering supplement for dealing with the ups and downs of life.
