Speech-language pathologists can earn the Certificate of Clinical Competence in Speech-Language Pathology (CCC-SLP), offered by the American Speech-Language-Hearing Association. Certification satisfies some or all of the requirements for state licensure and may be required by some employers.
The effect of lavender on sleep has also been studied. The inhaling of lavender odour during sleep has been observed to reduce the respiration frequency (you breathe in and out less), which is commonly used as an indicator of relaxation and sleep depth.
Lavender is LIKELY SAFE for most adults in food amounts. It's POSSIBLY SAFE when taken by mouth, applied to the skin, or inhaled in medicinal amounts. When taken by mouth, lavender can cause constipation, headache, and increased appetite. When applied to the skin, lavender can sometimes cause irritation.
