Alterative;  Astringent;  Disinfectant;  Diuretic;  Expectorant;  Laxative;  Poultice;  Salve;  
Tonic.

Tamarack was employed medicinally by a number of native North American Indian tribes who used it to treat a variety of complaints[257]. It is little used in modern herbalism. A tea made from the bark is alterative, diuretic, laxative and tonic[4, 222]. It is used in the treatment of jaundice, anaemia, rheumatism, colds and skin ailments[222, 257]. It is gargled in the treatment of sore throats and applied as a poultice to sores, swellings and burns[222, 257]. A tea made from the leaves is astringent[4, 222]. It is used in the treatment of piles, diarrhoea etc[222]. An infusion of the buds and bark is used as an expectorant[257]. The needles and inner bark are disinfectant and laxative[257]. A tea is used in the treatment of coughs[257]. A poultice made from the warm, boiled inner bark is applied to wounds to draw out infections, to burns, frostbite and deep cuts[257]. The resin is chewed as a cure for indigestion[222]. It has also been used in the treatment of kidney and lung disorders, and as a dressing for ulcers and burns[226].
Other Uses
Disinfectant;  Fibre;  Resin;  Tannin;  Wood.

Resin is extracted by tapping the trunk. It is obtained from near the centre of the trunk[171], one properly made borehole can be used for 20 - 30 years[64]. The resin has a wide range of uses including wood preservatives, medicinal etc. The hole is made in the spring and the resin extracted in the autumn[64]. The roots have been used as a sewing material in canoes and to make durable bags[257]. The bark contains tannin[229]. Wood - very strong, heavy, hard, durable even in water. It weighs 39lb per cubic foot and is used for telegraph poles, fence posts etc[46, 61, 171, 226, 235]. The roots are often curved by as much as 90° and are used by builders of small ships[226].
Cultivation details
Landscape Uses:Specimen. Prefers an open airy position in a light or gravelly well-drained soil[200]. Plants are intolerant of shade[226]. Tolerates acid and infertile soils and waterlogged soils[200]. Succeeds on rocky hill or mountain sides and slopes[200]. A north or east aspect is more suitable than west or south[1]. This species is very cold-hardy when fully dormant, but the trees can be excited into premature growth in Britain by mild spells during the winter and they are then very subject to damage by late frosts and cold winds[1]. Hybridizes freely with other members of this genus[200]. Planted for forestry in Europe[50], they are not suitable for this purpose in Britain[1]. Growth is normally slow in this country with average height increases of less than 30cm per year[185]. The trees are generally not long-lived[185]. Planting them in boggy soil may improve growth rates[185]. Open ground plants, 1 year x 1 year are the best for planting out, do not use container grown plants with spiralled roots[200]. Plants transplant well, even when coming into growth in the spring[200]. Plants in this genus are notably resistant to honey fungus[200]. Special Features:North American native, Wetlands plant, Attractive flowers or blooms.
Propagation
Seed - sow late winter in pots in a cold frame. One months cold stratification helps germination[113]. It is best to give the seedlings light shade for the first year[78]. As soon as they are large enough to handle, prick out the seedlings into individual pots. Although only a few centimetres tall, they can be planted out into their permanent positions in the summer providing you give them an effective weed-excluding mulch and preferably some winter protection for their first year. Otherwise grow them on in the cold frame for their first winter and plant them out in early summer of the following year. The seed remains viable for 3 years[113] If you are growing larger quantities of plants, you can sow the seed in an outdoor seedbed in late winter. Grow on the seedlings in the seedbed for a couple of years until they are ready to go into their permanent positions then plant them out during the winter.
