- SULFUR FREE PROCESSING
Strict traditional guidelines for the correct processing of herbs is followed to ensure effectiveness and decrease side-effects.  To decrease the need for preservatives the herbs are sterilized with heat or special high pressure alcohol steaming to rid the herbs of unwanted organisms.  Also, no irradiation or gas is used at any stage of processing.  All herbs are vacuum packed.  Finally Plum Flower injects the outer package with harmless nitrogen to further prevent spoilage.

- CLEANLINESS AND HYGIENE
The herbs are exceptionally clean, and are subject to a very careful grading and sorting system.  Impurities are carefully monitored to make sure there is no extraneous matter (no soil, powder, pebbles, or dust).  Also outside labs additionally test for microbials, heavy metals, pesticides and sulfite residues.  In addition the herbs are shipped in vacuum packages which further protects them from impurities during the shipping process.

- SHELF LIFE AND FRESHNESS
By omitting preservatives (which offer a shelf-life of 24-36 months), Plum Flower brand reveals their freshness and quality.  In contrast, commercial sulfured herbs look unchanged 5 to 6 years after purchase making it difficult to tell how fresh they truly are.
