Only Bitters Cinchona Succirubra MILLED POWDER 250gm


Only Bitters have gone out to procure the best Cinchona Bark for making your own Tonic Syrups we could find.

The milled powder is from the Cinchona Succirubra (Red Cinchona) bark from Guatemala. We source from a reputable sustainable farm that grows and harvests their own Cinchona trees. The bark sections from each tree are harvested once every 3 years for a term of 60 years.

The powder from Cinchona Succirubra is naturally high in Quinine Alkaloids. See table below for a difference between the cinchona varietals.

Table: Alkaloid Content Comparison by Cinchona species


Total Alkaloids (%)

Quinine Content (%)

C. calisaya

         3 - 7

            0 - 4.0

C. pubescens

      4.5 - 8.5

            1 - 3.0

C. officinalis

         5 - 8

            2 - 7.5

C. ledgeriana

         5 -14

C. succirubra

         6 -16

            4 - 14

Warning: Quinine Alkaloids could be toxic in high doses. Please do not exceed recommended dosages in parts per million when making your tonic syrup. As an example the US FDA and German authorities regulate that quinine be limited to between 83-85 parts per million (83-85 mg/L).

We have engaged a food scientist to determine conservative safe quantities for the use of this Cinchona Succirubra.  How to Make Your Own DIY Tonic (e-Book) is available for $1 with any purchase of a cinchona product from our store (or for $4.95 on its own).

While we do not endorse the quantities used, here are some publicly available Tonic Syrup recipes found on the web to help you on your way:

Bought some milled cichona bark for the creation of a tonic water. And this stuff brought all the flavour I needed to lay down a great base to build the botanicals on.

Exactly what i needed
