Question 1

Which extraction method is best suited for obtaining volatile aromatic compounds from herbs?

Accepted Answer

Steam distillation

Answer

Steam distillation is the standard method for extracting volatile aromatic compounds (essential oils) because it separates them without degrading heat-sensitive constituents.

Question 2

A client with a sensitive stomach needs a bitter tonic formula. Which preparation best mitigates GI irritation while preserving bitters activity?

Accepted Answer

Glycerite of the bitter herb

Answer

A glycerite uses glycerin as the solvent, which is gentler on sensitive stomachs while still extracting bitter compounds effectively.

Question 3

In a 1:5 tincture ratio, what does the '5' represent?

Accepted Answer

5 parts solvent to 1 part herb by weight

Answer

The second number in a tincture ratio represents the volume of solvent (in mL) per gram of dried herb, so 1:5 means 1 g herb per 5 mL solvent.

Question 4

Which herbal preparation would deliver the highest concentration of water-soluble polysaccharides from astragalus root?

Accepted Answer

Long-simmered decoction

Answer

Polysaccharides are large, water-soluble molecules best extracted by prolonged simmering (decoction), not by alcohol or short cold infusions.

Question 5

When formulating an adaptogenic tonic for long-term use, which delivery form is most practical for daily compliance?

Accepted Answer

Standardized extract capsule or powder

Answer

Standardized extract capsules or powders are convenient, shelf-stable, and consistent in dosing, making them ideal for long-term adaptogen protocols.
