Their products are excellent, some of my clients use them, and results are very good. About complaints...people who have difficult chronic health problems certainly cannot get healthy if they buy only one remedy, so I believe that many people expect too much and instant results, while not understanding how natural healing works. F.e. many people also try to save money on remedies, so instead of buying 3-4 remedies they need, they buy only one (one is cheper then 3) and when things do not work, they start to complain.
In addition, majority of natural remedies cannot work if people are at the same time using certain medications.
Native Remedies are OK, but people need to have wise approach towards self-healing.
Of course, for some conditions, as insomnia, Native Remedies do not have the best solution.
