Dosage Guidelines

For those new to tinctures here is some general guidelines on dosages and creating a custom prescription. If you have any questions regarding email angela@drforan.ca in order for it to be added.

What is the concentration of the tinctures?
The concentration varies depending on the herb and how it was prepared. Some are 1:1, 1:2, 1:3 and 1:5. A 1:5 ratio means 5ml of tincture is equivalent to 1g of dried herb. 1:3 is a stronger concentration since 3 ml of tincture equals 1g of dried herb. Currently all single herbs are a 1:2 concentration while Classic Formula tinctures are 1:3. We are working towards preparing most single herbs as liquid extracts to achieve a 1:1 ratio and thereby ensuring the best possible quality.

What solvent is used and at what percentage?
Shanti Solutions alcohol only based tinctures are manufactured with either vodka or grain alcohol. The percentage of alcohol used ranges from 25% to 90% depending on the chemical constituents to be extracted. Although we do not label custom formulas with alcohol percentages this information is available upon request. In the spring of 2013 we will begin carrying some glycerin based tinctures in the Classic Formulas line only.

How to determine the proper dosage?
The dosage varies according to age and the concentration of the tincture. The following dosages are based on a 1:5 tincture. Please adjust the dose according to the concentration a higher concentration ie. 1:2 or 1:1 use a smaller dose. Always start at the lower end of the dose range and only give more if necessary.

For a 1:5 ratio the average adult dose is 1-4 ml (20 – 80 drops) 3 x day. A low dose is 0.5ml – 1ml (10 – 20 drops) 3 x day. A high adult dose is 5ml to 15ml 3 x day.

The table is a guideline for dosages based on a 1:5 concentration. For children and the elderly a proportion of the full adult dose is given.

 Age Proportion of full adult dose Individual dose in drops:

6-12 months: 0.01 – 0.05 1 – 5 drops

1-2 years: 0.01 – 0.1 1 – 10 drops

2-5 years: 0.02 – 0.2 2 – 20 drops

5-10 years: 0.05 – 0.4 5 – 40 drops

10-16 years: 0.1 – 0.8 10 – 80 drops

Adults: 0.3 – 1 30 – 100 drops

Elderly: 0.3 – 0.75 30 – 75 drops


How to create an effective tincture formula?
If you are creating a custom prescription or modifying a common formula work in percentages. It is easy to adapt a formula to 30ml, 60ml or 120ml when the herbs are in percentages totalling 100%. Keep in mind prescriptions with fewer herbs are more suitable for tinctures as the therapeutic dose is considered to be 1ml/herb for 1:5 tinctures. As the number of herbs increases the dosage may need to be increased in order for a therapeutic dose of each herb to be reached.

Here is an example using a 6 herb formula with a 5 ml dose (1:5) with all herbs being the same the dose per herb is 0.83ml, just under the therapeutic dose. Changing the formula dosage to 7.5ml will increase the dosage of each herb to 1.25ml putting it in the therapeutic range.

For stronger concentrations the therapeutic dose per herb is less. For 1:3 the therapeutic dose is 0.6ml/herb, for 1:2 it is 0.4ml and 1:1 is 0.2ml.
