Other Notes

When using juniper leaf extract (primarily referring to essential oils and active ingredients obtained from juniper branches, leaves and fruits via distillation or solvent extraction), the following precautions must be observed: it must not be used by pregnant women, breastfeeding women, infants and young children, or those with impaired liver or kidney function; those with a history of allergies should use it with caution; when taken internally, the dosage must be strictly controlled; when used externally, it must be diluted and a patch test carried out beforehand. The following provides a detailed explanation for each usage scenario.

Key contraindicated groups

• Pregnant and breastfeeding women: Juniper extract may stimulate uterine contractions, increasing the risk of miscarriage; its components may also affect infants via breast milk. It must be strictly avoided.
• Infants and children: As their nervous systems are not yet fully developed, high-concentration essential oils may cause discomfort. Low-concentration formulations must be used under medical supervision, and contact with high-concentration products must be avoided.
• Individuals with impaired liver or kidney function: Components in the extract, such as terpenes and alkaloids, are metabolised by the liver and kidneys. Prolonged or excessive use may place an additional burden on these organs, potentially leading to elevated transaminase levels or abnormal urine output.

Precautions for topical use

• Must be diluted: Direct contact of essential oils with the skin may cause irritation or allergic reactions; it is recommended to mix them with a carrier oil at a ratio of 1:20 before using for massage or application.
• Perform a skin test first: Before first use, test on a small area behind the ear or on the inner wrist; observe for 24 hours. If redness, swelling, itching or a burning sensation occurs, discontinue use immediately and wash the area.
• Avoid broken skin: Do not use on areas of skin with ulcers or breaks. As the tincture contains alcohol, it must not be used on broken skin on the scalp.
  Avoid contact with mucous membranes: During use, prevent the solution from entering the eyes or mouth. When using for steam inhalation, maintain a safe distance of at least 30 centimetres and do not exceed 15 minutes per session.

Oral Administration and Dosage

• Strictly control dosage: Oral administration must be carried out under the guidance of a TCM practitioner based on pattern differentiation; do not exceed the recommended dose or take the medicine for prolonged periods on your own. The standard course of treatment generally does not exceed 7 days to 2 weeks.
• Be alert to accumulation and toxicity: Prolonged or excessive use may cause toxic components to accumulate in the body, leading to gastrointestinal irritation symptoms such as nausea, vomiting, abdominal pain and diarrhoea; in severe cases, it may affect the nervous system.
• Be aware of drug interactions: Concomitant use with anticoagulants (such as warfarin) may increase the risk of bleeding, whilst use with sedatives may enhance central nervous system depression. Those currently taking antihypertensive or antidiabetic medication should consult a doctor.
