Question 1

How does Picrasma excelsa work as a digestive tonic?

Accepted Answer

Picrasma excelsa contains intensely bitter quassinoids, including quassin and neoquassin, which stimulate bitter taste receptors on the tongue. This triggers a vagal reflex that increases gastric acid secretion, bile flow, and digestive enzyme production, enhancing overall digestive function. The same quassinoid compounds also demonstrate antimalarial activity by interfering with parasite protein synthesis. Evidence Level: C (preliminary research and traditional use support these mechanisms).

Question 2

Is Picrasma safe to take during pregnancy?

Accepted Answer

No, Picrasma excelsa is contraindicated during pregnancy and should be strictly avoided. The quassinoid compounds have documented emmenagogue properties and may stimulate uterine contractions, posing potential risks to pregnancy. Traditional evidence and available data (Level C) classify it as unsafe for pregnant women. Women who are pregnant, trying to conceive, or breastfeeding should not use Picrasma preparations in any form.

Question 3

What is the recommended dosage for Picrasma wood tea?

Accepted Answer

The traditional adult dosage for Picrasma excelsa wood tea is one cup daily, prepared from a very small chip of the dried wood. For tincture preparations, the recommended dose is 1-2ml daily. Due to its extreme bitterness—one of the most bitter substances known—larger amounts may cause toxicity and are not recommended. Start with the smallest effective dose and never exceed recommended amounts. Evidence Level: C (traditional use).

Question 4

Does Picrasma interact with antimalarial medications?

Accepted Answer

Limited clinical data exists on specific drug interactions with Picrasma excelsa. Due to its documented antimalarial properties, there is theoretical potential for additive or conflicting effects when combined with conventional antimalarial drugs. The bitter compounds may also affect absorption of oral medications. Patients taking antimalarials or other prescription medications should avoid concurrent use without medical supervision. Evidence Level: C (theoretical based on pharmacological activity).

Question 5

What are the side effects of taking Picrasma?

Accepted Answer

The primary side effect of Picrasma excelsa is its extreme bitterness, which frequently causes immediate nausea and taste aversion. Excessive doses can trigger vomiting and have documented toxicity. The wood is so intensely bitter that it has been historically used as a natural insect repellent and denaturant. Other potential effects include gastric irritation. Users should strictly adhere to recommended dosages and discontinue use if severe gastrointestinal symptoms develop. Evidence Level: C.

Question 6

What conditions is Picrasma traditionally used to treat?

Accepted Answer

Picrasma excelsa has been traditionally used for malaria treatment and prevention, as a digestive tonic to stimulate appetite in cases of anorexia, and topically for head lice infestations. The antimalarial activity is attributed to quassinoid compounds that interfere with parasite development. While these uses are supported by traditional practice and preliminary research, clinical evidence remains limited (Level C), and conventional treatments should not be replaced without medical guidance.
