A 64-year old white man complained of fugax amaurosis for less than 1 h on two occasions spaced 2 days apart, with arterial blood pressure readings of 200/120 and 220/130 mm/Hg, respectively. He used a daily sachet of an instant preparation of Ginseng Forte-Dietisa (500 mg Korean Ginseng or Panax ginseng) during 13 days for asthenia. There were no other prescribed or unprescribed drugs or herbal products or drugs of abuse. Upon examination, blood pressure was 195/95 mm/Hg. The rest of the vital signs were normal, as were heart auscultation, chest X-ray, carotid Doppler ultrasound and brain-computed tomography. Visual acuity, colour vision, visual fields, pupils, ocular motility, intraocular pressure, biomicroscopy and funduscopy were normal. One week after cessation of the P. ginseng product, his blood pressure returned to its previous level (< 140/90 mm/Hg). After 1 year of follow-up the patient remained normotensive. The authors believe that a causal relationship between Ginseng Forte-Dietisa and fugax amaurosis/transient ischaemic attack is probable in this case.
