Smrekovit Ekstra spruce resin ointment with cooling effect  is a completely natural ointment. It combines the effect of spruce resin and the cooling effect of camphor and menthol.  
The key ingredient of the product is spruce resin so the main difference to Smrekovit Klasik spruce resin ointment is that Smrekovit Ekstra ointment contains camphor and menthol, which provide the cooling and the mild anaesthetic effect. These ingredients, however, don't affect the effectiveness of the product, so the product has the same strength as Smrekovit Klasik.  
The effectiveness of spruce resin has been confirmed by the many experience of users which followed the spruce resin ointment discovery in 1990. Spruce resin nourishes the skin externaly and internaly and improves its natural defence, function and blood circulation.  
The product is available in 50 and 150 mL plastic jars.
