What is the 'ortho effect'?
- This phenomenon is termed the ‘ortho effect’, and is well- documented [17-28]. Interactions of vicinal groups in the M+. of various derivatives of substituted benzoic acids initiate various types of hydrogen and skeletal rearrangements, and generate multiple fragmentation processes. As a result, for
Are there any side effects from Dr Ortho Products?
- Since Dr. Ortho products are Ayurvedic, there are no possible side effects from these herbal products unless the user is allergic to any particular herb present in the contents of the product they are using. For the optimal pain relief, we also have a balm for pain relief , Pain Relief Ointment, and a Pain Reliever Spray.

What are the effects of orthographic processing?
- However, the most obvious impact is on the writing, the speed of writing, and the spelling of words. Those with orthographic processing issues have difficulty remembering sight words; they tend to guess words incorrectly. Orthographic processing issues are the brain's inability to retain simple words and sight words to recall when reading.
