Balm of Heaven
Umbellularia californica
Umbellularia californica, commonly known as California bay or Oregon myrtle, is a native tree of the Pacific Northwest. While its traditional use in medicine has not been extensively documented, it plays an important role in local ecosystems and cultural practices. Scientific studies have shown that U. californica can passively close its stomata under extreme drought conditions, independent of abscisic acid (ABA) levels, which suggests a mechanism for water conservation. Additionally, early increases in ABA levels correlate with the onset of stomatal closure and reduced transpiration during periods of drought. Browsing by animals significantly altered some leaf traits but did not affect stem anatomy in both Quercus agrifolia and U. californica. In another study, U. californica enzymes were used to engineer Chlamydomonas reinhardtii for the production of medium-chain fatty acids, indicating potential applications in biotechnology. Safety-wise, no major issues have been recorded for U. californica. There are currently no reported drug interactions with this plant either.

What the science says
- The study found that early increases in abscisic acid levels correlated with the onset of stomatal closure and reduced transpiration in U. californica during drought, before significant changes in soil or plant water status.
- Browsing significantly altered some leaf traits but not stem anatomy in both Quercus agrifolia and Umbellularia californica.
- Umbellularia californica can passively close its stomata under extreme drought, independent of ABA levels.
- The study engineered Chlamydomonas reinhardtii to produce medium-chain fatty acids using enzymes from Umbellularia californica and other sources, achieving stable production in small and large-scale cultures.
