How to use saffron correctly: When not to take it – and when it is particularly helpful

November 09, 2025

Brief introduction: Saffron is generally well-tolerated as a spice in small quantities (e.g., a few threads in tea or food). The following cautionary notes refer primarily to high-dose extracts/dietary supplements – not to normal culinary use.

When should saffron not be taken (or only after consultation)?

pregnancy
In high doses (significantly above typical kitchen amounts), saffron can stimulate the uterus. Therefore, pregnant women should not take high-dose supplements without medical approval. Normal amounts of saffron are not considered a problem.

Blood thinners / bleeding tendency
There is a case report of bleeding with rivaroxaban + saffron supplement . Anyone taking anticoagulants/antiplatelet drugs should consult their doctor beforehand (kitchen quantities are generally exempt from this).

Before operations
As with many plant extracts, it's advisable to pause supplements 1–2 weeks before surgery (to avoid bleeding/anesthesia interactions). Kitchen quantities are usually not critical – if in doubt, ask the team.

Low blood pressure / Blood pressure medication
Saffron can slightly lower blood pressure . If you are prone to low blood pressure or are undergoing treatment, monitor it closely.

Allergies
Rare cases of spice allergies, ranging from mild to severe reactions, have been reported. If you have a known spice allergy, only test under medical supervision.

Breastfeeding & Children
There is little robust data for the breastfeeding period ; for children/adolescents, some studies exist (see ADHD below), but the general rule is: consult your pediatrician before taking the medication .

Interactions
Saffron affects neurotransmitters , among other things; consult your doctor if you are taking psychotropic medications (e.g., SSRIs/SNRIs). Clinical problems are rarely reported, but caution is always advisable.

Toxicology / Overdose
Studies using 20–30 mg of extract per day for 4–8 weeks are generally considered to be well tolerated. Very high amounts of spices (in the gram range) can be toxic – this is far outside the kitchen.

What can saffron help with ?

Depression / Mood (mild–moderate)
Several studies and meta-analyses show noticeable improvements – some comparable to standard therapies in short-term settings.

PMS/PMDD & Period Pain
Randomized studies report significantly fewer PMS symptoms .

Sleep quality

ADHD
Initial studies in children/adolescents show improvements , comparable to methylphenidate in small studies – early evidence , therefore always medically supervised.

Multiple sclerosis (MS)
The data is still limited . There are indications of improved antioxidant markers and improvements in mood/quality of life in one RCT, but no confirmed effects on disease progression.

Blood pressure / cardiometabolic markers
Meta-analyses suggest slight reductions in blood pressure and inflammatory markers.

Practice: safely take

Start low: e.g., test 20–30 mg of saffron extract per day for 4–8 weeks; continue if well tolerated (consult your doctor if you are taking medication).
Kitchen ≠ capsule: Spice amounts in food/tea are fine – the caution above refers to high-dose supplements .
Quality matters: Look for lab tests and genuine origin (counterfeits exist). Overview: https://www.news-medical.net/health/Saffrone28099s-Evolving-Place-in-Modern-Medicinee28094From-Tradition-to-Evidence.aspx News-Medical

Why saffron is still a strong choice

Saffron combines well-being (mood, sleep) with culinary enjoyment – especially in small everyday rituals (tea/iced tea, cooking). With good quality and the right dose, it can be effective and beneficial , provided you take the special cases mentioned above into account.

simple conversion from mg to saffron threads (rule of thumb):

1 thread ≈ 2 mg (typically 1.5–2.5 mg depending on size/moisture).
1 g (1000 mg) ≈ 450–600 threads.

Quick table

10 mg ≈ 4–7 threads
20 mg ≈ 8–14 threads
30 mg ≈ 12–21 threads
50 mg ≈ 20–35 threads
100 mg ≈ 40–70 threads

Practical tip

For 1 small cup of tea/iced tea : usually 3-5 threads are sufficient (≈ 6-10 mg).

For 1 large cup of tea/iced tea : usually 8–12 threads are sufficient (≈ 15–25 mg).
For 2 large cups : 15–20 threads (≈ 30–40 mg).
A “pinch” of product often corresponds to 10–15 threads (≈ 20–30 mg).

Important NOTE

This conversion applies to threads (raw material). mg values for capsules/extracts cannot be directly converted to threads because extracts are standardized (specific active ingredient concentrations).
In sensitive situations (pregnancy, medication, surgery, etc.), the following still applies: kitchen quantities are okay , caution refers to high doses .
