Research in a number of medical publications, such as the European Journal of Nutrition, links bone disorders such as fractures to acid—base imbalances.8 In his book Beautiful Bones Without Hormones, Dr. Leon Root states, Even a small drop in the body s pH can cause a dramatic increase in bone loss. 9 Remember that a drop in pH means an increase in acidity.

So, what mechanism does the producing plant use to avoid the effects seen on other species Does the plant avoid accumulation of the compound by secreting it almost as quickly as it produced, in a manner similar to that of Sorghum species that produce the allelochemical sorgo-leone only in root hairs that secrete it rapidly. Apparently this is not always the mechanism, as Berlin et al. [165] indicate that although the dry...
