Ingredients

  • St. John's Wort-infused oil — 50ml

  • Lavender essential oil — 8 drops

Instructions

  1. Combine oils in a glass bottle and shake to mix.
  2. Massage gently over the affected area.
  3. Avoid sun exposure on treated skin for several hours — St. John's Wort can increase photosensitivity.

Notes

Increases skin sun-sensitivity — avoid before sun exposure.

Interactions & contraindications

St. John's Wort-infused oil

Full profile
  • CNS medications (benzodiazepines, SSRIs, MAOIs) — may potentiate sedative or serotonergic effects

Pregnancy

Avoid

St. John's Wort has hormone-modulating activity and significantly interacts with many medications (it induces liver enzymes that metabolize a huge range of drugs) — generally avoided in pregnancy, and any use requires medical coordination given the interaction risk alone.

Breastfeeding

Avoid

Some case reports describe infant drowsiness/colic when the nursing parent used St. John's Wort; combined with its extensive drug-interaction profile, it's generally avoided while nursing.

Children

Avoid

Not typically used in children given its significant drug-interaction profile and hormone-modulating activity.

Antidepressants (SSRIs, SNRIs, MAOIs)

Combined use raises the risk of serotonin syndrome.

Hormonal birth control

Induces liver enzymes that break down oestrogen, reducing contraceptive effectiveness.

Warfarin and other blood thinners

Speeds up drug metabolism, reducing effectiveness and clotting protection.

Immunosuppressants (cyclosporine, tacrolimus)

Can lower drug levels below the therapeutic range — a serious risk for transplant patients.

Triptans and other migraine medications

May increase serotonergic side effects.

Arnica-infused oil

Full profile

Pregnancy

Use Caution

Topical use on unbroken skin (creams, gels) is widely used for bruising/muscle soreness in pregnancy; oral/internal arnica is toxic and always contraindicated regardless of pregnancy status.

Breastfeeding

Likely Safe

Topical use on unbroken skin is considered compatible with breastfeeding; avoid the chest/nipple area. Oral arnica is always contraindicated.

Children

Use Caution

Topical use on unbroken skin is commonly used for children's bruises; oral/internal arnica is toxic and must never be given to children.

As a member of the Asteraceae (ragweed/daisy) family, this herb carries a real chance of cross-reaction in anyone allergic to ragweed, chrysanthemums, marigolds, or daisies — introduce cautiously if there's a known allergy.

Blood thinners (topical use)

Even topically, high-dose or broken-skin use can have systemic anticoagulant effects; oral use is not recommended at all.

Lavender essential oil

Full profile
  • CNS medications (benzodiazepines, SSRIs, MAOIs) — may potentiate sedative or serotonergic effects

Pregnancy

Likely Safe

Aromatherapy and mild tea use are widely considered safe throughout pregnancy; internal use of concentrated lavender oil/capsules is less studied and generally kept to topical/inhaled use instead.

Breastfeeding

Likely Safe

Aromatherapy and topical use are considered compatible with breastfeeding; avoid direct application near the nipple/areola before nursing.

Children

Use Caution

Diluted aromatherapy is commonly used to help children sleep. Repeated topical exposure in prepubertal boys has been raised as a possible (though not conclusively proven) factor in rare cases of hormone-related breast tissue changes — avoid regular, undiluted topical use.

Sedatives

Additive drowsiness, particularly with oral use.
