HARVEST TIME:
Late May to early June, when the plant is mature and rich in active compounds.

HARVEST METHOD:

A trench 10–15 cm deep is dug around the plant to access the stem-root junction.

Special astragalus knives are used to cut the plant obliquely.

The exuded resin (tragacanth) darkens and solidifies, then is collected after 21 days.

The cutting process may be repeated every 2–3 days to maximize yield.

CONSERVATION (STORAGE):

Dry in shaded, ventilated areas or ovens not exceeding 40°C.

Stems should be green, bitter, and odorless when dried.

Ideal moisture content: 12%.
