Powder is extremely susceptible to contamination by mould and bacteria. It is highly sensitive to moisture and grinding into fine particles considerably increases penetration of micro-organisms and oxidation of the active molecules!

We recommend that only Artemisia annua and Artemisia afra be used in herbal teas.

However, powder is useful and effective for the production of capsules and tablets, in combination with food and even in production of suppositories.

if necessary, the ground material in hermetically sealed containers in a cool, ventilated and shaded location.

Care must be taken to avoid overheating (of the shredder or any other method of grinding) as this causes the loss of volatile molecules and therefore reduces the efficacy of the Artemisia!
