Get a Blue candle and dress with some healing oil , In Your specific case I would use figural candle of appropriate gender.
Pray for that person. Lighting a candle and praying is one of the best methods, as simple as that.
Healing oil ( In Conjure traditions ) should contain Solomon seal root , Thyme , Mint , Allheal , Sampson Snake root, Msater of the Woods , Selfheal and some of the oils : Sandalwood , Ylang Ylang , Amber ( Gives strenght, courage, life will and alike ), Camphor or Cedarwood ( Cleansing and health work )
Healong oil ( In European witchraft ) should contain Juniper berries , Rosemary and Sandalwood oil ( Cunningham , Scot ).
In Europe , particulary Eastern there is a tradition of making simple cake with honey and heling herbs for the sick , while prayers are said for their healing. Everyone that wishes health to person in subject is called to stir the cake. The herbs traditionally added are strong healing herbs such as Selfheal , or Lemonbalm or Sage.
Hope it helps , blessings
