Juniapa-hinojo sabalero

BOTANICAL NAME
piper auritum H. B. K.

FAMILY
Piperaceae

CULTIVATION CONDITIONS
Grows wild in abundance in open areas in tropical Central
and Southern America. ...

YIELD AND DESCRIPTION
On steam distillation leaves give a mobile clear liquid with a
characteristic odour of "root beer". Yield of oil has been
reported at 0.17% with a safrole content of 70% (Gupta).

MAIN USES
As an alternative to sassafras oil or as a source of essential
oil containing Safrole ...

In Panama it is used as a food condiment and as a fish bait
(Joly). In Mexico it is used as a house plant because of the
heart shaped colourful leaves.

CULTIVATION
Natural cultivation as secondary vegetation after clearing the
high perennial evergreen forest.

PRE-TREATMENT
Wilting prior to distillation is required

PROCESSING METHOD
By hydrodistillation of the dried herb. Water/steam or steam
distillation is satisfactory. The temperature of the condensate
is critical as emulsion or top/bottom separation can result.

The sun dried exhausted herb can be utilized as a fuel.

COMPOSITION OF OIL
Safrole up to 90%

Terpenes
Forty components have been identified (Gupta)

The oil is available, but it's quite expensive. If you can cultivate it, it would be a great source. Oil costs 240 usd for 4 oz.

We'll soon find out if I'm a chemist or not!

      Can piper auritum bee cultivated?  Bookmark   

Polythene Sam was kind enough to repost parts of my "Who Eats Parsnips?" thread after the Zonez folded.

If you are fortunate enough to live in a warm moist region, the more relevant question is not whether you can cultivate Piper auritum, but whether you can stop its propagation when you decide you've got enough safrole for now.



It is grown and/or wildcrafted throughout Mexico, half of Texas, and Central America as a food plant. It is also naturalized in a lot of places (Florida, Hawaii, Samoa, Fiji) it's not wanted. That's because the people in those places don't know how to bake fish in it. It is the herb Hoja santa.

      grows as far north as zone 8  Bookmark   

Piper auritum grows as far north as zone 8 - check out:

USA Zone Map (http://www.gardenweb.com/zones/zonemap.html)

European Zone Map (http://www.gardenweb.com/zones/europe/)

But it will grow slowly up here. An ambient day temperature of up to 35C is OK for them (greenhouse). They like lots of water. Foliar feed once a week. A garden full of them might get you as much as 1 oz of sassy oil a year (or so I estimate). I can't yet tell because I don't have a garden full of them!

propagation is by:
a) suckers
b) cuttings
c) seeds

Suckers - Difficult to take suckers without damaging the root system of the parent plant - which will retard the growth of the parent plant. Not recommended unless you have at least 5 underground shoots to repot. Don't expect the parent plant to do so well for at least a month afterwards as it repairs it's roots.

Cuttings - Easy. By 'cutting' I mean taken from a shoot above ground. When a side branch has at least 3 leaves it can be cut as near to the main stem as possible. Wet base. Dip in hormone to depth of ~ 15mm. Put in wet vermiculate (soaked once a day thereafter). Keep pots in moist incubator. Mist leaves as often as possible. Roots form in 2-3 weeks. Examine after 3 weeks. Plant out in peat-compost after roots are at least 25mm long.

Seeds - Who can say where you can find them. I'll post a list of suppliers here but don't even try until the Autuum. Seeds may not be produced by plants grown outside their normal environment and may not be fertile unless first digested by a Costa Rican bat!

Note: this can only be a hobby to all but the farmers here.
