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.
Anyways, Tea Tree Oil (Melaleuca Alternifolia) is a gift to humanity: 1  Tea tree oil contains strong anti-viral properties. 2  Tea tree oil also is a broad spectrum anti-fungal (3) . 3  Lastly, tea tree oil is a potent anti-bacterial agent (5) . There is promising data for the treatment of herpes simplex labialis and other viruses as well (1)(2) . 2  Tea tree oil also is a broad spectrum anti-fungal (3) . 3  It has been shown to combat a wide variety of fungi in controlled experiments. 4  This is why it is commonly used traditionally for toe fungus.
