Query: Warning: Can Cause Serious Complications

Two months into a 3-month herbal detox which included Elemis Deep Drainage, Cal-Metab Plus, Vitality, and Silhoutte, I started feeling nauseated, headaches, off-balance, dizzy, insomnia, night sweats, fatigue, increased heart palpitations, hot spots on my skin, confused, memory loss, high blood pressure which is not norm for me. Looked up ingredients one by one and found that 3 different ingredients had the side-effects I was experiencing so I stopped taking the supplement.Docs are testing kidneys, pancreas, liver and gallbladder and feel my body was stressed by the detox which may take up to 3 months to get back to norm.I had no weight loss even with exercise and diet plan in place.
