Should I avoid all aromatherapy oils?

Some strong aromatic oils, in particular eucalyptus and camphor (in ointments such as Tiger Balm, Vicks Vapor Rub, etc.) have been shown to have a negative effect. Please also avoid the use of undiluted aromatherapy oils such as tee tree oil and menthol during the course of your treatment (i.e., those with especially strong odors). Milder oils such as lavender and rosemary diluted in bath or massage oils are fine, as are colognes and perfumes.
