After the publication of the study [1] we noticed a substantial error in our published article. In the original article [1] the dosage units were erroneously described in μg instead of mg. All references to μg quantities should be replaced with mg quantities throughout the manuscript. Also the LD50 should be g/kg instead of mg/kg.

Thus, in the abstract section:

The 3rd paragraph, 4th sentence, under the caption: Results and Discussion: one should read 40 mg/mouse instead of 40 μg/mouse.

In the results section:

The 5th paragraph, 2nd, 5th and 6th sentences, under the caption: Evaluation of toxicity and safety of phytol adjuvants: replace μg with mg (in three places),

The 5th paragraph, 4th sentence, under the caption: Evaluation of toxicity and safety of phytol adjuvants: replace 8 mg/kg with 8 g/kg

Figure 4 Legend, (under the caption: Demonstration of splenomegaly in mice treated with different adjuvants), lines 6 & 7: replace μg with mg (in four places)

Table 1 (next line beneath the table heading): Dose (mg, NOT μg), and LD50 (g/kg instead of mg/kg).

Table 2 (counting the Table heading): lines 6 and 7: (80 mg NOT 80 μg)

Table 3: Footnote (first): 140 mg (NOT μg) of each substance was used.

Correction of the above errors in units does not alter the basic findings or conclusions of the original article.
