Biota Orientalis as a Healing herb

Biological Description

Biota has lots of names: Biota, Biota orientalis, Thuja, Thuja orientalis, Oriental thuja, Platycladus orientalis, Platycladus stricta, Oriental Arborvita. All these are Biota’s scientific names. This is a famous Chinese healing tree (or Chinese cedar) that belongs to the Cypress family (or Cupressaceae). In China Biota is called bai zi ren. Thuja orientalis is sometimes confused with Thuja occidentalis (Eastern Arborvitae, Arborvitae, American Arborvitae, or White Cedar) that also belongs to Cypress family, but looks differently ( it is conical in shape and is native to North America) and has other health benefits.

Thuja (or Biota) is a general term for trees of the genus Thuja(or differently called Aborvitae).

Biota grows as either a large shrub or a small tree. It starts growing from very little size up to very broad, but not high pyramidal tree. The tree form of Biota usually forms a central stem and develops into a 4 – 6 m tree, unlike the shrub form that is more commonly seen.Biota has scale-like leaves and little inconspicuous monoecious flowers (individual flowers are either male or female, but both sexes can be found on the same plant).All year it is in leaf (evergreen), and the seeds ripen from September to October. The flowers are pollinated by Wind.

It has a moderate growth rate and will grow well in full or partial sunlight. This is, actually, the reason it is widely planted, as it tolerates humidity, heat, drought, and alkaline soil (much better than American Arborvitae) . What does it prefer?

The leaves and the stems are used in traditional Chinese medicine as a sedative – to treat nervous disorders, insomnia, heart palpitations, and was a nice help in emotional depression and restlessness. It is a general remedy for nourishing heart and calming mind. That is also a reason why Biota is recommended for treating asthma and bronchitis.

When Biota oil is used in aromatherapy, a few drops are mixed with several ounces of safflower or another vegetable oil for massages, a few drops can be added to bath water. This kind of hydrotherapy is really comforting before sleep after the hard working day.
