The study of vibrational effects is ongoing, relevant and significant. Below is an excerpt from an excellent discussion of ultrasound exams for pregnant women. It covers many aspects of the issue. In particular, below, it discusses some of the dangers.
"Studies on humans exposed to ultrasound have shown that possible adverse effects include premature ovulation, preterm labour or miscarriage, low birth weight, poorer condition at birth, perinatal death, dyslexia, delayed speech development, and less right-handedness. Non right-handedness is, in other circumstances, seen as a marker of damage to the developing brain. One Australian study showed that babies exposed to 5 or more doppler ultrasounds were 30% more likely to develop intrauterine growth retardation (IUGR)- a condition that ultrasound is often used to detect."
2-Phenoxyethanol and Vibrational Healing
This team of process engineers at Annaba University in in Annaba, Algeria ran a series of experiments to determine if sonic waves could degrade or diminish concentrations of 2-phenoxyethanol in water. They found that it did indeed have a significant effect.
You can find the abstract of their study here:
I don't know that we can necessarily use the exact same process that they used. The conditions in the body are significantly different from those in the lab. But the general implications are profound. Vibration has an effect.
