Rarouni can be eaten, but it is best to cook it and eat it. Guarouni is better to eat it after frying because of its high oil content. Juniper has the effect of quenching thirst, diuretic, and suppressing cough and expectorant. The seeds contain fatty fatty oil; the fruit contains triterpene saponin , organic acids, resins, sugars, pigments; the roots contain proteins, saponins, acids. Its fruit, pericarp, kernel (seed), and rhizome are all good Chinese herbs and can be used in medicine.

Pharmacological effects

Antibacterial and anticancer effects. Juniperus communis has certain inhibitory effects in vitro against Escherichia coli, Sonnet's dysentery bacillus, and Proteus mirabilis. The water infusion (1:2) also has different degrees of inhibitory effects on certain skin fungi in vitro. In an in vitro test, the whole Juniperus communis decoction (20% decoction) had a lethal effect on ascites cancer cells.

And it has been suggested that both rarouni bark and rarouni kernel are effective, but the former is better. The seed husk and fatty oil are not effective. Alcohol and ether extracts are also effective. 60% alcohol extract has the best in vitro effect. However, in animal tests, its effect is less significant and unstable; in vivo, the effect on sarcoma is a little stronger than that on ascites cancer cells.

Rarouni kernel contains saponins, organic acids and their salts, resins, fatty oils and pigments. Fatty oil imitation is 26%, of which saturated fatty acids account for 30%, unsaturated fatty acids account for 66.5%, with rarouni acid (trichosanic acid) as the main one. In addition, the seed oil also contains andrographic acid, which may be the special piece of components in the seed oil of Juniperus spp.

The fruit of Juniperus communis contains triterpenoid saponins, organic acids, resins, sugars and pigments. The seeds contain fatty oil. The fruit contains proteins that are different from those contained in its tuberous root, asparagus, see asparagus strips.
