An example of a linear equation with three variables, x, y, and z, is given by: ax + by + cz + d = 0, where a, b, c, and d are constants and a, b, and c are non-zero. Linear equations occur frequently in most subareas of mathematics and especially in applied mathematics.
One study has shown that tea tree oil is more active against the organisms associated with transient carriage than against commensal skin flora and thus may be useful in eliminating the transient flora while suppressing but maintaining commensal flora. 21 The rapid kill rate of Clone 88 compared with standard tea tree oil shown for most of the organisms tested in the present study is encouraging and suggests that further clinical studies should be carried out.
Tea tree oil dose and instructions for use. Tea tree oil is only a topical treatment - it should never be taken by mouth. Because tea tree oil is an unproven treatment, there is no established dose. The concentrations of tea tree oil used in studies have varied depending on the medical condition. For instance, a 5% tea tree oil gel might be used for acne, while a 10% or higher tea tree oil cream might be used for athlete's foot. A 100% tea tree oil solution has been used with toenail fungus. If you use tea tree oil, follow the instructions on the label or get advice from your GP, pharmacist or herbal specialist.
