  • Horse Chestnut Seed Oil balances the circulation in the skin and promotes a clear skin with an even complexion and good skin tone. It has a slight astringency which enhances these effects. Use in anti ageing creams, lotions and serums.
  • As well as this, it is one of the best oils for combatting spider veins on the face and legs. Blend with high Omega 3 oils for best results.
  • Horse Chestnuts contain a saponin called Aescin which has a very anti inflammatory effect on the skin. Use in irritate and acne prone skin skin products.
  • It is the first choice oil to use if you get swollen ankles from fluid accumulation or have tired and heavy legs from prolonged standing. Using gentle, upward massage strokes on the legs can bring a lot of comfort. Aescin has a protective effect on the collagen and elastin which tones the underlying tissues.
  • This is the same function that makes Horse Chestnut Seed Oil so popular amongst athletes as a topical application on acute sprains during sporting events to alleviate localised swelling and bruising. This is enhanced when it is combined with Arnica Oil.
  • Horse Chestnut Seed Oil in a massage oil blend is superb for pre and post massage sessions. It can relieve the aches from stiff joints and the massage improves overall performance.
  • It is an excellent oil to use in Gardeners Hand Creams or Winter creams as it helps to boost the circulation to the extremities and stop the fingers getting too cold.

Hair Care

  • The high level of Stearic Acid in Horse Chestnut Seed Oil means it will be excellent at cleansing excess sebum from the scalp whilst conditioning the hair without making it feel lank or heavy and with no sticky residue. This also protects the hair shaft from damage. Use in shampoos and conditioning hair packs.
  • The exceptionally high level of Omega 9 essential fatty acids keep the hair shaft soft and supple and stimulate the growth of stronger hair that is thicker and longer, without breakage.
  • The improvement in the microcirculation of the scalp improves blood flow to the hair follicle for optimum growth conditions.
  • As it conditions the scalp so well, dandruff is kept under control.

Historical Information
When the leaf of the tree is broken off at the joint with the stem, the end looks like a small horseshoe - hence the name. The conkers were also used as horse feed.

    I’m hopeful!

    Bought this to turn into a balm for my spider veins. Too soon to know if it works but it’s a very nice product to use.

    I have used this Company several times and have been very happy with the products I have purchased and the speed and efficiency with which my orders have been dealt with. Although the Horse Chestnut Oil is recommended for skin care, I have used it to deter spiders in my house, particularly in the kitchen and garage. It seems VERY effective for this use - I am no longer troubled with visits from spiders, large or small. I have purchased other oils and been very pleased with them. I particularly like the Raspberry Seed Oil and the Sweet Almond Oil (excellent for soothing and smoothing hands and improving appearance of nails.
